Nanny Needed - Full-time / Part-time

We are looking for a great after school nanny for 2 children, 3 and 5 years old, in Dorchester Center. The main hours would be about 3-5 p.m. to get kids from the bus stop and watch them until I get home. However, open to as much as 25 hours a week for someone who would come early and do light housework and meal prep before the bus. A drivers license is a plus but not necessary.
