Thrifty purchasing...

It sounds like you're conflicted about what you want - some of your posts sound very "snake rescue organization" and some sound more like "snake breeder" -- if you have a knack for rescue/rehabilitation/rehoming, that's a really important niche! It could be financially neutral with some reasonable adoption fees and a good network of veterinarians and foster homes. Just don't mix the two. When I bring home a stray cat, I don't plan to breed it - there are plenty of stray cats who already need homes. I still bring home stray cats...

There are thrifty ways to cut costs, like purchasing bowls at thrift stores; making hides (freezer boxes are awesome); Buying rats in bulk (frozen); Using newspaper or bulk bedding. I even assembled my own quarantine tank out of an old aquarium, some plexiglass & flex tape.

There are great ways to cut costs without sacrificing the animals' safety and while producing valuable offspring.
