Nanny Needed For 3 Children

We are looking for a full time nanny for 3 children. Our oldest is in 2nd grade, so care for her would be minimal during the school year. We also have a preschooler who goes for 1/2 days Monday-Thursday. Then an almost 3-year-old who doesn't attend preschool until the fall. Hour requirements would change at that time, with of course full time days in the summer. Our current nanny of four years will be relocating in February with her husband, who is in the military. We would prefer someone who could help out with light housekeeping and meal preparation. We are looking for someone who has their own car, who does not smoke and who is willing to drive children. However, a vehicle will be provided while at our home to transport the kiddos.
