Babysitter Needed for my Children - Now Hiring

We are looking for a great nanny for backup care on days our babysitter cannot cover for our 1-year-old. We also are looking to establish a relationship with someone for evening care on the weekends for 2 children in Los Angeles. We would prefer someone who could help out with light housekeeping when kids are asleep. We would prefer a nanny who has their own car, who does not smoke, who is comfortable with pets and who is CPR certified.
