Babysitter Needed for my Children - Now Hiring

I have 3 girls ages 7, 10, 11 and am looking for someone to pick the 7 year up from school and potentially take the girls to after school activities on Mondays and Tuesdays. It would be great if we could also get all day help on school holidays/in service days from 8:15-5:30. The two older girls are self sufficient and walk home from school. Responsibilities aside from pick up and transportation to activities include checking homework, and potential light cooking/heating up food.
