most likely NOT be able to find pygmy chameleons in your locale. Your most realistic option is to purchase off the internet. I can reccomend LLLReptile. They usually have R.Brevs in stock, and if not get them in soon. They have a very nice facility, and although the chams are wild caught, the are treated for parasites.
What kind of research have you done? Have you purchased supplies?
ALso, for lots of information check out the Yahoo Group Brookesia!
