There are some very useful threads on fundraising around here. I’d take a look at those. But grants can make a huge impression. I might try to look into sponsorships/ partnerships with local businesses if your school would allow it, but that might be kind of a stretch.
Just be ready for all the work it’ll take. You don’t need assistants, but, from my experience, they help. And can maybe carry themselves eventually when you’re gone/leave them.
Best of luck to you if that’s the route you decide to take!
