Well, the first thing you have to do is establish a reputation for quality animals. Participation on the forums, like BP.net will get people familiar with you. Vending tables at local Expos is also a good way to get the word out. You can also join a local Herp club to get to know local enthusiast. Develop relationships with local breeders. The most important thing is to provide great animals and exceptional service. You do all that and you should have no problems selling.
