Follow and pay attention to already successful breeders.
BHB Reptiles, Mark Mandic, Justin Kobylka and, so on.
The Reptile Report held a talk at the CRBE here in Toronto last year that was very informative and, I am sure a great resource for anyone considering the leap from hobbyist to full time breeder.
I may even have footage from that around here somewhere.
EDIT: It is honestly amazing just how much info these people are willing to share so freely. Some may sit on projects until they prove out but, they all seem to enjoy sharing their passion for these animals
