Babysitter Needed for my Children - Full-time / Part-time

We are looking for an after school nanny to look after our two girls, (age 7 - 2nd grade) and (age 5 - preschool). Wed like them to work from 2 p.m. -6 p.m. Mondays and Wednesdays with some flexibility on the end time. This will involve pickup from school/the bus stop, taking to activities some days and playing at our homes other days, and occasional dinner prep.
