Babysitter & Transportation Needed For 2 - 4 Children In Chadds Ford.

We are looking for a great babysitter for 2 (sometimes 4)children in Chadds Ford. Looking for after school pick up (can use my vehicle), homework if applicable, then transportation to and from activities when necessary. We require a babysitter who does not smoke and who is comfortable with pets. 2 kids, and potentially on one day, 2 additional kids would be included. School is about 15 minutes from home. Time requirements would be to arrive at school by 2:45pm, and then would be done by about 6:30 p.m. unless we request additional time to go out to dinner.
