Nanny Needed For 2 Children

We are looking for a great nanny for 2 children. We need someone who can take and pick up our preschooler from school. We would like someone who could help out with light housekeeping and cooking (for the children). We would prefer a nanny who does not smoke and who is CPR certified. Grandmother will be in the house to help but she is unable to physically pick up the children.
