Babysitter - Full-time / Part-time

We are looking for a great recurring babysitter for 2 children in Shoreline. Looking for someone who can help at least few hours a day on some weekends (often we will be home too) and possibly some week evenings for date nights. Could be great for a student. We would prefer someone who could help out with light housekeeping. We would prefer a sitter who has their own car and who does not smoke. We have two cute kids. One is 2. 5 and one is 6 mos.
