Late Afternoon / Evening Family Helper Needed In SF

We are looking for a family helper who can help us with dishes, kids laundry, cooking for kids, bathing kids and tidying up around the house. There may be a few occasions where driving is needed to pick up the girls (age 5 and 6). We need someone who is available at least 20-30 hours per week. Typical hours would be 2-8 p.m. on the weekdays but at least one day (usually Friday) where we'll stay out until 10-11 p.m. for date night. Our ideal person is someone who lives in San Francisco, at least 26 years old or older, doesn't mind doing house chores, loves playing with kids, has a clean driving license for at least 5 years, has a flexible schedule and is very reliable.
