Babysitter Needed for my Children - Full-time / Part-time

We are looking for a great nanny for our 2-year-old child in Oakland. We need coverage on Fridays only, 6-7 hours, starting at 7:30am, from August till the end of May. We would prefer a nanny who has their own car (our location isn't great for public transit), who does not smoke, who is comfortable with cats and who is CPR certified.
