I'm by no means a breeder, so feel free to ignore my opinion if you choose. I did however run some numbers to see what the costs and revenues would be for breeding snakes. I couldn't see any way to make a living selling high-volume snakes without a huge reputation, and a big committment. That's your relatively common corns, kings, ball pythons morphs...snakes that go for $100.
There are higher end snakes that it seems could give you a living. Albino ball pythons (females in particular) sell for thousands. If you had a breeding pair, you would make some money for a while on those. The problem as I see it is that you have to get in early, and you have to spend some money. They wont be rare forever...a couple generations and the high end market is getting saturated.
