You should do more study on how genetics work.
My wife was starting to talk about breeding corn snakes. We like them and already have this gorgeous female sunkissed-diffused het charcoal corn named Cirice. She's a total peach and I simply adore her. She cost $300 a few years ago and I'd buy her again without hesitation. So, the wife saw palmetto corn snakes for sale, saw that they go for $600 -$1000, and started to see dollar signs just like you said you are. She though that if we got a male palmetto we could breed him to our female and produce litters of some crazy morph worth hundreds of dollars each. A quick primer on corn snake genetics sobered her up, fast.
The fact of the matter is, due to how corn snake genetics work, none of the progeny from such a pairing would be any morph at all. They would all be visually normal, though they would be triple hets. In other words, our $300-$600 snakes would only produce offspring worth less than $100 each and that is if we could sell them. After all, selling snakes isn't like selling kittens or puppies!
BP genetics are totally different but my point stands. You are grossly underestimating how common it is to produce $500 snakes. Granted, $200 snakes are going to be easier, but that brings me to my final point. That snake that costs $200 today, in three to four years (when your theoretical female is ready to produce) that same snake will only cost $100 or so. Why? Because there are lots of people producing BPS for a relatively small market, and the rare morph of today is common tomorrow. The first albino BPs were bizarre anomalies and sold for thousands, now you can get a female albino at any expo for less than $200.
Again, the only reason to breed is because you love snakes and breeding is a cost effective method of getting more.
Allow me to echo everyone else on this forum. Look to get one female for now and see how it goes. But please do lots of research first!
