Babysitter - Full-time / Part-time

We are looking for a great nanny for my children in Pennsburg. We would prefer someone who could help out with light housekeeping. We would prefer a nanny who has their own car, who does not smoke, who is CPR certified and who has a college degree. I am postpartum with a newborn. I would need assistance with taking my children to/from preschool (1 goes MWF and 1 goes WF) however we would need all 4 to drive in the car as I can not lift. I have a vehicle to accommodate all 4. Then you would bring the others back here and play, light housekeeping, etc prior to needing to pick up again.
