Afternoon Babysitting/Driving in Woodley Park - Mon & Weds @Family Babysitting/Driving

I am looking for an afternoon babysitter who can drive my 8-year-old son to gymnastics practice weekly on Mondays and Wednesdays, starting immediately. We live in Woodley Park in DC and his gym is in Bailey's Crossroads, VA. Our babysitter would need to drive our car or your 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 4:00-5:30PM. I'm looking for someone who is a responsible driver with good references.
