Just remember to do right by the dogs first and foremost. Aside from that, litters aren't cheap. You have to deworm them on schedule, and vaccinate them all before they are ready to be sold. Some folks who will be paying a high price for a pup may want a health certificate done by a Veterinarian. Are you going to offer a health guarantee? Also, are you planning on selling them to pet or show homes? Or working homes? The main way I would imagine you getting your name out there in regards to your dogs depends on what genre of buyers you are targeting. Show or pet homes, show the hell out of the parents and have them earn as many accolades as you can. If you're targeting folks who will want them as catch dogs, you gotta get out there and work them two parents and they'd better prove themselves to be bonafide hog catching machines. Especially when there are a decent amount of proven Dogos out there that are well established as hog dogs already. If I want a pup for a working purpose, I'm gonna go to they guy/girl that has proven working parents, not a random person that is breeding just to sell pups. Hopefully something in my post will help you out with what you are seeking advice on.
