There really isn't a market in the sense that you are not going to be able to make money selling leo's. Especially if you cannot ship them.
Persoanlly i would look into shipping info and learn how to ship leos before getting the breeding pair. That way you can sell them easier.
Try and find people in your town who would be interested in purchasing a leo from you.
If there is a reputable herp store, or pet store with a really nice herp dept ask them if they would be interested in buying, or trading leos for store credit.
Definately do all this breeding the leo's, normal leopard gfeckos can be harder to get rid of than you might imagine
good luck!
