Sitter Job in Mansfield, Ohio

My son is 7 years old and he loves to play outside. We live in the back of the neighborhood where he can play on the street. It's behind Chipotle in Ontario. I am looking for someone to watch him in my home during the week 9-430 but the hours will vary. Sometimes it will only be for a few hours and Mondays will be 9-430. I am a single mother on a limited budget. I am willing to pay $2.50 an hour for the summer. Once school starts I won't need a sitter as often.
