Childcare Needed - Full-time / Part-time

We are looking for a great babysitter for 1 child in San Francisco. We would prefer a nanny who does not smoke, who is comfortable with pets (we have a friendly cat) and who is CPR certified. We need help in July and August outside of 9-5 to help with care before and after camp, and with getting too and from camp (muni is fine). We have a fun 5yo girl. Bonus if you can speak Spanish with her!
