There are a number of programs out there to get "2nd career" people into the classroom. I suspect you might be better off going that route than the straight-in route as I believe most states require a MS now (or is that just the high school level?).
Yeah, we helped put together a pool table and ping pong table Sunday night (after kid bed time) in exchange for pie. In the end, we were tired and over fed, so we put together the tables in exchange for some conversation (me) and an opportunity to use tools (DH).
It would have been an otherwise horrible job for the two of them to do. They could have done it, but it would have been a pain and (as kerc also identifies) a marriage tester. This way it was pretty fun. And we know that one or both of them would help us out if we needed something similar.
