when you start out, dont expect profits. even if you make some money with some hatchlings, you will have invested more in the BPs, incubator, hatchling rack, and everything that comes with it.

so you should be in it with your heart.

also, i think its the wrong question to ask which morph to choose in order to make money. when you have experience in getting snakes to breed and have some nice proven females ready to go, then it makes sense to spend a really large amount of money for some fancy new gene and to try to produce fast enough to keep up with falling prices. so you should ask which morphs will produce the most beautiful stuff you can afford, and thats quite a personal question. maybe something like albinos or BELs or piebalds or different codominants, and the base morphs you will need later on. the genes that have come down in price but that dont go out of fashion simply because they work really well. pastel, black pastel, fire, mojave, pinstripe, spider, enchi, ..... to really make use of some extremely expensive BP, you need to have some of the basics covered and have a breeding operation running first.

so choose genes and BPs that you visually like and that can produce combinations that you like, and that are good sellers, and go for the really expensive genes later on.

that is, if you decide to go for BPs, i see you have not yet decided what species to choose for breeding. for example corn snakes are a bit easier to breed and they produce more eggs and reach maturity faster, and you can get multi-gene morph combinations really cheaply. im not saying anything against ball pythons, just want to point out, there are many options besides BPs. anyway, i wish you the best of luck
