How much money you would need depends on what your goals are. The bigger the dreams, the bigger the wallet you will need. Just jumping into this as a business takes DEEP POCKETS. Starting small and working your way from there is very time consuming but the least costly. As a hobby, it's expensive. As a business, I couldn't even imagine. I don't even want to know how many snakes I'd have to produce and sell every year to pay all of my bills. Seems to me like it would take a lot of the fun out of it.

But, to answer your question about how much do I think it would cost, I would imagine 40k+ to be able to do it full time.
