I am planning on catching a wild gravid female garter this summer and I have a very good plan on selling the babies. I was wondering though...

1. Will the new babies have parasites when they hatch?
2. would $30 be a good price to sell agarter snake?
3. Will I make a decent sized profit from selling them?
4. Can they be kept in large numbers as babies?
5. When should I start feeding the new babies?

sorry for all the questions but I need to know lol.

(be warned, more questions may come)
