Babysitter Needed

We are looking for a great babysitter for 2 children in Chelmsford. We would prefer someone who could help out with light housekeeping and homework help. We would prefer a babysitter who has their own car and who is CPR certified. This would be for a few afternoons a week, some weeks may not be needed due to on / off travel schedule. Hours would roughly be 3:30-7 the latest. Must be comfortable taking the kids to soccer/swim practice which is local to our home.
