Ill be honest, if you have 12 grand sitting around, why do you still need your parents permission? How many is a "decent" amount of snakes? Think about it in the long run. Have you breed bps yet? How quickly did they sell? do you have the space for all these babies you plan to hatch?Feeding them? Do not waste money now thinking about how much you "could" make selling the babies. If you just thinking about money to me your in the "ball game" for all the wrong reasons. Ball pythons start as a hobby/passion then can possible turn into a job, not the other way around IMHO. I think you need to sit down and do some thinking, and see if you want to spend 12k on a snake. If you do more power to you, just dont look at it as a a quick way to get your money back.
