Tutoring? It has the advantage of flexible hours and high pay for the time involved.

I tutored both Latin and Greek in college; I hadn't thought of picking it back up again because I assumed the market would already be saturated with under-employed, overqualified students of the humanities. I realize as I type it out that even if this is true, I should still see whether people want to employ this particular under-employed, overqualified etc. I have no idea how to go about making myself visible. (This is part of the problem.) I should find out what the high schools around here even teach.
