My friends who breed snakes, one in particular (i estimate he sold $30-40,000. In snakes last year ) Uses facebook to promote his snakes. He posts an availability list every couple days, and posts any pictures as he goes through the year about what he is working on. Before anyy of his 3 monthly shows, he posts in those groups what he will be bringing.

Also variety is the spice of life, think of adding a few boas, burms, , colubrids or whatever. Retic morphs are pretty hot right now, and boas seem to be pretty steady over the years, to what you produce and you can expand your customer base.
