I have seen several members here from Texas. I'll bump this up for you and maybe one of them will see it and be able to help you out. You could also check the classifieds at the top.
I know of a pet shop owner on long island who told me that he personally knows several different types of cham breeders in texas. here is a link to his website and you can contact him personally.
his name is MArc Marrone and I would recommed direct phone contact because they never answer any of my emails.
