Well,
It depends on what projects you want to work on. I would say at least grab one male and a Adult Female Normal. You can get the male ready to breed in 6months at least. If you do this you can at least have one pair that can probably breed this year.
Pastel,Yellowbelly,Pinstripe,Mojave,Lesser,Butter,Enchi,Fire and the list goes on!
I think you can do a lot better with that amount of money by checking out Garrick Demeyer at royal constrictors. He charge $50 for shipping no matter how many snakes you order and he have breeding groups on sale!
