Don't know the size of your town(?) but you could most likely make some very nice pocket change as a tutor or sub teacher.
Well, the ideal situation would be for us to find a Catholic school that will make us a deal where the wife and I fill one "full-time slot" (we're both PhD chemists--and Catholic), with each of us working half-time.
subs actually get more per day than a full-time teacher normally.
