Afterschool Babysitter Needed For 3 Children

I am looking for a great caretaker for 3 sweet sisters: ages 6, 8 and 10. They're curious, active and bright children who love to read, explore nature, play sports and games and imaginative play. I would prefer someone who could help out with light housekeeping and who has their own car, who does not smoke, who is comfortable with an old sweet dog and who is CPR certified. Schedule will be every other Mon & Tues or Wed & Thurs (alternating).
