What you described is not a rescue. It is great that you want to use them for education. But I would contact a rescue and get herps from them. This way you are giving animals a home and won't get in over your head. 4 or 5 enclosures ready to go is not really a rescue, just a few empty cages
I think that for the time being, i would just take in the animals you need for the programs and concentrate on education. A rescue is alot more time, money, and work than you can imagine. Good Luck Bro.
