I want to get a pair of Jackson Chameleons. Where can I find a breeder that is local to me? How did you find your Chameleon?

What do you think of buying a male and female from the same breeder, assuming that I breed the Jacksons some day?
I don't really trust the breeder to actually give me a male and female from different parents. How would I know, right?
