Childcare Needed

I am looking for an afternoon babysitter who can drive my 8-year-old son to gymnastics practice weekly on Tuesdays and Thursdays. We live in Woodley Park in DC and his gym is in Arlington in VA. Our babysitter would need to drive our car or their own car to pick him up from our neighborhood school, give him a snack in the car, and make sure he gets to practice on time. The hours would be approximately 4:30-6:15 p.m. I'm looking for someone with childcare experience who is a responsible driver with good references.
