Babysitter Needed for my Children

We are looking for a great nanny for 2 children in between Antioch and Discovery Bay. We would prefer a nanny who has their own car, who does not smoke and who is CPR certified. I work at 6:00 a.m. so we would need someone who could watch the children at their residence from about 5:30 a.m. till about 3:00 p.m.
