Babysitter Needed For 2 Children In West Chester

I'm looking for someone who can pick my teenagers (15-year-old boy and 13-year-old girl) from high school at 3 and take them to their activities and then bring them back home around 6. We will provider van for transportation. So overall about 3 to 5 hours of work depending on the day and their activities. If we like the service, we would even go full time as long as school is open. For full time, we would probably go with dropping them to school by 8. This is a great opportunity for someone who have extra few hours and want to make some money just by driving around.
