I would talk to your local breeders and buy animals from them when it's time to get additional snakes. That way they know you're out there. Establish relationships with them. Once you have some hatchlings, you could ask one of them if it would be ok to share a table at an expo in the future. After I bought from one local breeder several times, he told me that it would be fine to share a table eventually. I think people are more willing to buy from small breeders if they see the animals in person, so an expo might be the perfect place to start. My plan is to start by selling on Kingsnake, Fauna, on my own website and at expos. I've noticed that a lot of breeders on here have their logos and a link to their website in their signature, and I think that's an excellent idea if the signature is well designed.
