Congrats! This looks very cool at a glance.

I tutored math for extra cash in grad school, and I was almost exclusively hired by well-off local families so that their their high schoolers could improve from an A-minus to an A, ace the AP Test, test into Calculus 2 at UMich, and have a leg up getting into the business school. I loved talking about calculus every day, but it felt like I was participating in a weird arms race between these parents, and upholding a status quo that I really don't agree with.

Tutoring other students in undergrad was much more fun and rewarding -- even though the pay was 1/6 the rate -- because it was paid for by the university and anyone could walk in and get help.

I hope this turns out to be sustainable, as I'd love to give some of my time to it.
