Babysitter

We are looking for a great babysitter for 3 children in Greensboro. We would prefer someone who could help out with light housekeeping. We would prefer a babysitter who does not smoke and who is CPR certified. I am looking for help starting out one afternoon a week. I put Thursdays, but I am flexible to the day. It would be from 1:00 (when my 3-year-old girl gets out of preschool) until possibly 6:00. My 7 and 5-year-old boys would get home around 3:45 from school. If this works out, I am also possibly looking to add morning help to get kids ready for school and out the door (7:30-9am).
