Nanny Needed For My Children

We are looking for a great nanny for 2 children in South San Francisco. We would prefer someone who could help out my mom while for a few hours in the evening after school/daycare while My husband and I are on vacation. We would prefer a nanny who has their own car, who does not smoke, who is comfortable with pets ( 1 small Friendly dog in the home) and who is CPR certified. Looking for short term but if a great fit may become more of a part time gig?
