Are there any colleges or college students wanting to be teachers near you? When I was attending college for teaching, I always needed students. We had the homework club where I helped students with their homework. I had to do this as an alternative to some field work because I work during the day. As for their after school activities, do they have parents that carpool the kids? You can try that or if not already set up try speaking with the other parents.

Goodluck!
