Research any zoos and even rescues in the area, most do pay people to care for the animals in their care.
Doing small shows like 4thesnakelady mentioned is a great idea as well, but you really NEED to be insured to
do that. If someone were to get bitten or squeezed too tightly, in their eyes, you could have a law suit in your hands.
Lets face it, we LOVE to sue each other.
Good Luck
