Hi everyone, I just found a site called Laborfair.com, which connects people looking for tutors, plumbers, housekeepers, etc. with those who provide such services. I just registered in the tutor section, and it's really easy to do. You just set yourself up with a profile, including a photo and description of yourself, and the jobs literally come to you. It's great for earning extra revenue on the side, (especially during the summer) or if you're between jobs. You can specify your hourly rate and everything. It works by using ratings and reviews, so it's kind of like a blend of ebay and craigslist. Right now it's only in California -- SF Bay Area, L.A., Sacramento, and Stockton/Modesto. Plus it's free, so you have nothing to lose.
