I've worked with Tiki Tiki Reptiles and LOVED them...got a super healthy cham that acclimated incredibly well to his enclosure immediately. Chad was super on top of everything and always ready for any question, he got back to me ASAP each time I had a question. Shipping was great, packaging was great as well. Definitely recommend them.
You are pretty well off with all of the site sponsors but I'd definitely recommend Tiki Tiki as would many others
I would buy a chameleon from a member of the forums at https://www.chameleonforums.com/chameleons-sale/ . Just make sure that you ask the breeder to give you more info on the chameleon, just in case. Also if they live around the area you could do a local pick up.
