What other people have said about starting small is absolutely true. My boyfriend and I kept bps for two years before moving into breeding them, and even then, we started SMALL with just six high quality, single gene animals. We bought them all as hatchlings, so it wasn't until three years later that we could even being pairing. We found a respected local breeder willing to mentor us through the process so we could also learn from his experience, and I'd recommend everyone try to do something like that if they're able to.
Interestingly, he was mentoring someone else around the same time. The other man he was mentoring went out and bought a TON of snakes, all with multiple genes, many as proven breeders so he could start right away. Four or five years down the road, and that guy has sold his collection for dirt cheap and is out of the hobby. Our mentor told us he wasn't surprised because he advised him against breeding too many snakes and/or more expensive morphs when starting out, but the guy went ahead and did it anyway. Our mentor was right. No one wanted to buy from him because he had no reputation (just a random guy suddenly appearing at our local reptile show selling expensive snakes).
On the other hand, we're still going strong and growing every year! In the time that we were raising up our snakes, we were volunteering at our local expo to meet people, and learning more and more. It is hard being patient, but it really pays off! At this point, we basically sell every clutch within a month of their hatching, and have been able to invest in some of the fancier morphs we fell in love with with we got into the hobby! I'm glad to hear you're going to wait to breed your snakes. If you can wait longer than a year, I'd recommend it! There is so much to learn in this hobby and your customers will get more from it and be better keepers themselves when you have more experience to share :-)
