side hustles or other ways to make money while in vet or med school?

I know this doesn't belong here but I never get responses anywhere else 😂 but what are some you can think of? I'm starting vet school in 2018 and my husband is looking into med school. We'll take loans out for tuition but that's already going to be a ton so we're looking at our options for living expenses. Both programs are pretty tough so I don't think we'll have time for anything more than part time jobs or TA positions on campus. 
ETA: this was originally posted in CC but I realize it's in H&L now along with a similar post. Oh well. Also want to add how excited about it I am 😂 can't talk about it to many people in my personal life or on Facebook because he could be let go from his engineering internship if they realize he isn't going to be working for them after he graduates. He didn't sign a contract or anything but still. I was really dreading having to move somewhere that sucks and not having the chance to really get established somewhere since mining engineers (his previous chosen profession) move from mine to mine when each is done and of course coal and other minerals aren't stable. It would be so awesome to literally move anywhere we want, everywhere needs doctors or veterinarians! He isn't sure what he'd like to work in yet but I can see him being a general physician or something not very specialized, or oncology since he's known so many people who passed away to cancer. He may find something else he loves in med school though! He's going to continue with his engineering degree since it is entirely paid for by scholarships and it fulfills most of the requirements for med school, he just has to squeeze in some organic chemistry at some point or take an extra semester. I have 2 years of pre reqs for vet school. There are several colleges who offer vet and med so we're going to try to get into one of those. I want to work with small animals (dogs and cats mostly) and some farm animals 🐶🐱🐰🐷🐴
