Based on what I've read on the forums, from big breeder's blogs, and youtube channels, you really can't force ball pythons to do anything...
Sure you can try to offer rodents to your snake as often as possible, but then you run the risk of the animal going off feed! They will eat when they want to!
You can pair every single male to your female, but if she doesn't want to produce eggs, she won't! If they feel that they're ready, they'll go! If you had control over this, nobody would recommend buying MULTIPLE females in case one doesn't want to breed... Heck, same goes with males! Sometimes males are just not ready for the occasion!
Unless the person is literally force-feeding his ball pythons to grow up to size, it doesn't really bother me what everyone else is doing in their breeding venture... Their motives don't bother me either... You say they want to breed for money? How can they guarantee that they'll make money AND mistreat the animals? I want to breed to produce morphs that nobody has seen. I want to produce COOL morph combos, and not so much the 7-gene snakes lol. I'll consider myself successful if I was able to do all of this for free.. If I can hatch out an enchi pied that looks as good as the one in the Ozzyboids collection, I'll feel like I succeeded...
Whoever is breeding "for the money" is sadly misinformed LOL. They've got to be extremely lucky to be able to "get rich quick".
