I'm board member of the Reptile and amphibin society of Philadelphia (R.A.S.P.), we just started about 5 months ago. I can tell you it's not the easiest thing to do. You'll need some people really willing to dedicate some time to it.
If you have any specific questions about getting started I may be able to answer some of them just E-mail me at
