Sitter Job in Portland, Oregon

I am a single mother and I work 2-3 nights a week at a restaurant downtown. I need stable quality childcare from the hours of 4-11 (end time varies) for my son, in my house. You would be required to prepare meals, and clean up afterwards, but no real housework (unless you want to, i can pay a little extra for that.) Fisher goes to bed at 8:30, so there is some downtime for you built in, work on homework, etc. I don't have a t.v., but I do have wireless internet. I would prefer someone who leaves in northeast, or north portland.
