Babysitter - Full-time / Part-time

I am looking for a great babysitter for 3 children in San Diego for occasional nights and for week long work trips. I would prefer someone who could help out with light housekeeping, some cooking and who can bring the kids to school for my work trips. I would prefer a babysitter who has their own car, who does not smoke and who is comfortable with pets. We have a 3-year-old lab.
