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 yet. We are unsure as to when we would need this position filled, as our current nanny of four years will be relocating in the near future 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.
