May I suggest for those wanting to go back to work, but in this economy may have to wait it out, yet you'd like the extra money.
I am currently hosting foreign students going to Foothill and DeAnza College and have done so for over 15 years. They will pay you $800/month for room and board, breakfast (anything from toast to cereal) and dinner prepared by you 4 nights week(the weekends students can prepare it). You provide them with a private room, bathroom (okay to share) and live within 5 to 7 miles of school near a bus line so they can walk or catch a bus to school.
Please let me know you are interested in hosting.
