Weekday Nanny For 2 Children In Potomac, Afterschool Care

I'm looking for a great nanny for 2 children ages 4 (J ) and (L ) 5. Responsibilities would include daycare pickup at 3 p.m. (5 minute drive) and then waiting for the bus at 4 p.m. Tidying up and cooking (easy) meals for kids would be part of our caregiver's responsibilities. We are looking for help in the afternoons and could create a schedule with anywhere from 20-40 hours per week. We are open to working with a someone who can do either part-time or full-time. Please let me know which you would prefer.
