Like stated before time is a must!!!!! We have around 70 snakes, 15 females breeding right now plus some monitors and lizards. Then the 500+ rats/mice/asf/rabbits to feed them all. We both work two jobs as medics and all and I mean ALL of our free time when we get home,before work and days off are devoted to the reptiles and feeders. This business literally takes all of our free time. We love it and don't mind the work , but for someone in school or that likes having a life lmao its not for them. Not saying don't get into it. Just saying if you can't say for 100% that you can devote your free time everyday to your reptiles, then don't get that many.
Just with the list you posted first, that's enough to tie up all your free time.
Plus breeding isn't as easy as you think. It's a lot of work. Being able to incubate eggs and not lose them it s real JOB.
But I agree with doing some research and starting out small. Good luck.
