Breeding Feeders?

[Niatross]

I have just purchased a small colony of mice to breed for my own personal snakes. However there will be an excess and I'm wondering, how can I create a network of people around me? The only friend I have that owns a snake breeds her own as well. I'm looking for people to sell my mice to. I might even be willing to ship them frozen but I'm having a very hard time finding people who are interested. How can I find customers?
