URGENT: Looking for a babysitter for the summer - (Plymouth, MA)

I'm looking for a babysitter for the summer Mon. thru Thursday. 8am - 3:30. My son is eleven years old and is very active and loves sports. We have a pool and need supervision when he is out there. one day a week to do 1/2 - one hour of school work. We have a Yellow Lab Ret. puppy and a cat. Would like a car to maybe go to the movies once in a while or walk thru the mall. Looking to pay $10.00 hour.
