Starting and needing to breed

im getting ready to get three more ball pythons and want to start breeding my own mice can any one give me some starting ideas and how tos also where should i get the breeders from and what kind of set up would i need thanks for any input

funny but this is what i do, (our petco is seriously right next to petsmart) i run down to petco grab a handful of females and go to petsmart and grab my males or the other way around on the sex (i do this to reduce inbreeing my feeders, even though eventually they will become food) than i go get tubs from walmart and stick 1 male to every 3-4 females per tub. provide hides, lots of food, and water and everything else is pretty self explainatory
