What kind of business?
Breaking, retail, boxes, singles, vintage, modern?

What inventory do you already have? Do you plan to sell via eBay, COMC, Sportlots, myslabs, Facebook marketplace, PWCC, etc?

What level of investment are you willing to make?

Obviously being in Dallas, you have some advantages with local shows, card shops, and customer base. But your ability to buy cheap collections to flip will be difficult with so many competitors.

What is your main goal? To make a living? To turn your collection into money? Your request is a little too vague for people to help you with, IMO.

Lay out your basic concept of operations.
