What's Inside.

Not a hobby manual. A modern niche empire blueprint built around sports cards as the case study.

— Part 01 —

Mindset & Models

The 5-minute brain rewire that took me from $14K to $72K in 12 months. Plus the 4 ways to actually make money in this hobby.

"The cards are the costume."
— Parts 02-03 —

Legal + Money

LLC, EIN, business banking, sales tax, S-corp election — done in a weekend. Plus the cost basis math 90% of flippers screw up.

"Boring infrastructure is the price of real wealth."
— Part 04 —

Reading the Market

Hobby Math. The 4 numbers that decide if you make money. The 6 cycles I trade every year. Sports knowledge → six-figure profit.

"Amateurs trade hype. Operators trade cycles."
— Parts 05-06 —

Sourcing + Selling

The 7 goldmines I source 90% of inventory from. Negotiation scripts that buy $40K collections for $12K. eBay/Walmart/Amazon/TikTok/Whatnot mastery.

"Buy low or die."
— Part 07 —

The Repack Business Model

The exact math behind every Sports Repack pack. The 3-tier pricing model. How "Chasing Heats" became a religion.

"50% inventory. 50% theater."
— Parts 08-10 —

Grading · Strategy · Tools

PSA vs SGC by sport. The 6 buy-low triggers I set alerts for. The exact tool stack running my 7-figure business — for $200/month.

"Don't bet without checking the odds."
— Part 11 —

The Attention Economy

Why every card business is now a media company. The Sports Repack Flywheel. The 5-Layer Hashtag System. Hooks that go viral.

"Whoever owns the attention owns the sale."
— Part 12 —

The Dark Side of the Hobby

The chapter most ebooks won't write. Fake gurus, gambling traps, ego flex culture, scam repacks. Read it twice.

"It will eat you if you don't respect it."
— Parts 13-15 —

Community · Scaling · The Future

The "Best Family on Whatnot" playbook. When to hire your first helper. The 47 Rules. Where commerce is going by 2030.

"Customers buy once. Communities buy forever."
— Three Cinematic Moments —

The Stories Inside.

A taste of how this book actually reads.

"
— Introduction · The Cracks of Normal Life —

The $312 Night.

"It's 1:47 a.m. on a Tuesday in February 2022. The kitchen table is covered in penny sleeves, top loaders, and a tape gun with a half-broken handle. I open the Mercury app and stare at the number for a long time. Three hundred and twelve dollars."

"
— Chapter 21 · The Walmart Approval —

"They Said Yes."

"I was at my actual job, in a glass conference room on the 14th floor, in the middle of a quarterly review presentation, when my phone buzzed. The notification said: 'Walmart Marketplace: Welcome — Your application has been approved.'"

"
— Interlude · The Tilt —

The Boardroom.

"My Apple Watch buzzed against my wrist. Three short, one long. The Whatnot show I wasn't running had just generated more revenue in 60 minutes than my Q3 executive comp. I felt something quietly tilt. Like a planet shifting one degree on its axis."

— Chapter 44.5 —

47 Rules for Modern Niche Empire Builders.

A rant. Save the chapter. Re-read it yearly. Here's a taste:

02.
The cards are the costume.
05.
Most people don't fail because they lack opportunity. They fail because they never start.
08.
Liquidity beats grails.
14.
Audience is the moat. Inventory is the bait.
17.
Your face is your most valuable distribution asset. Use it.
25.
A great product is 50% inventory and 50% theater. Theater is not a dirty word.
30.
The treadmill stops the second you stop running. The flywheel keeps spinning even when you sleep.
31.
Most operators stop at inventory. Modern niche empires start at attention.
37.
Entertainment and investment are not the same thing. Tell your buyers which one they're paying for.
41.
The moments you almost quit are the moments your audience falls in love with you. Don't edit them out.
43.
The dream doesn't kill you. The pretending does.
47.
This isn't about cardboard.

— Who Wrote This —

The COO who built
a sports card empire part-time.

By day, I'm a senior tech executive — most recently COO of Data-Tech, one of the fastest-growing tech companies in Tampa Bay. 21 years scaling companies across Tampa, Orlando, Miami, and Boca Raton — finance, operations, acquisitions, executive leadership.

But long before any of that — I was an eight-year-old in Wellington, Florida, biking with my cousins to a card shop tucked next to an Eckerds drugstore. That's where this whole obsession started. Decades before Whatnot. Decades before "side hustle" was a phrase.

By night — and at 1:47 a.m., and on weekends I should've been resting — I built Sports Repack from a kitchen table into a near-million-dollar business in 6 years. Working 10-15 hours a week. Without ever quitting my day job.

This book is everything I learned, paid for, broke through, and built. The mistakes my younger self made. The systems my current self uses. The rules I wish someone had handed me at 22.

Who This Is For. (And Who It Isn't.)

$20 is cheap. $20 of your time isn't.

Buy It If You're:

  • An adult with a hobby you've quietly loved since age 12
  • A side hustler running an expensive hobby with a Stripe account
  • A 9-to-5 worker who can't shake the feeling there's a real business hiding in your obsession
  • An executive who wants the upside without quitting the career
  • A flipper who's making some money but can't break $5K/month
  • Anyone willing to spend 10 hours a week for 12 months on something real

Skip It If You're:

  • Already profiting more than $2,000/month — you don't need a starter book, you need to scale
  • Looking for a get-rich-quick scheme
  • Unwilling to spend $200 on basic tools and supplies
  • Going to quit after the first two bad deals
  • Allergic to showing up on camera, in DMs, in inboxes, in the work

FAQ.

Q.Why is the book only $20?

Because the lessons inside cost me about $1.7M to learn over 50 years (mine + my mentors'). Charging $20 is the only price that feels right for "everything I'd pay $1,000 to know at 22." Plus, cheap books actually get read. Books that get read change lives.

Q.Is this only for sports card people?

No. Cards are the case study. The frameworks (Modern Niche Empire, Sports Repack Flywheel, the 47 Rules) apply to any internet-native niche business — sneakers, watches, vintage Pokémon, candles, knives, coffee, even creator-led services. The deeper you read, the more you'll realize this is secretly a book about modern entrepreneurship.

Q.I'm already running a card business. Will this help me?

If you're under $2K/month profit — yes. If you're already profiting $2K+ monthly, you don't need a starter book, you need to scale. The Course (coming soon) is built for you.

Q.Do I need card industry experience?

Zero. The book starts at "register an LLC" and ends at "run a 7-figure business with systems." If you can read, click links, and show up, you can do this.

Q.How long does it take to read?

Cover to cover: a weekend. To actually execute: 30 days for the legal foundation, 60 days for first inventory, 90 days for repeatable revenue. The book gives you the 90-day roadmap.

Q.What if I hate it?

30-day refund. Read it, hate it, email me. Full $20 back, no questions. (For the record: this has never happened. But the guarantee is real.)

Q.Will this teach me to gamble on packs?

No. The Dark Side chapter (Part 12) is one of the most important parts of the book — it directly addresses the difference between entertainment and investment, and the responsible way to operate in this hobby. If anything, the book will make you smarter about avoiding the traps the hobby is built on.

"The internet didn't change the game. It changed who was allowed to play.
I wrote this book for people who are ready to play."
