Do know that a lot of breeders don't end up making much or any money back. A lot of them just lose money by becoming breeders.
I definetly recommend getting a baby BP and when it's old enough to breed then make your decision.
You say you love animals so much, but also consider would you have the heart to cull deformed snakes or pre-kill your own rats for picky eaters? This is why I would have a hard time being a breeder.
