Babysitter Needed

We are looking for a great babysitter for 2 children in San Francisco. We would prefer someone who could help out with light housekeeping and homework help. We would prefer a babysitter who has their own car because our home is in the Excelsior and public transit doesnt travel frequently enough. A few times a month we may ask for a few additional evening hours to cover for moms late night work. Would also pay extra time for light meal prep (like prepping and chopping ingredients for a nightly large salad.) Also laundry folding. I pay in 15 minute increments for in case we go over (or you spend extra time helping out around the house even though youre off duty with the kids.)
