Breeding ball pythons is not going to quickly make you money. You have to spend a great deal of time, effort, and money to make anything and even that will not be recouped for years. There are also the facts that morph popularity changes rapidly and what was a $1000 can be a $100 snake in no time as the industry gets saturated and tastes and trends change.
That said, I would not want you to get discouraged from eventually breeding ball pythons but coming in with the assumption that if you get certain moprhs that you will have geese that lay the proverbial eggs is just not the way to approach this hobby.
If you are ready for the commitment of a ball python (they live upwards of 30 years) then find one you like, take your time and ask breeders questions, watch youtube videos of top breeders like BHB, and above all else don't enter into this for the money.
I highly recommend watching this from Matt Gambrel at Olympus Reptiles. He nails on the head what it means to breed ball pythons as a business
