Babysitter Needed For 2 Children In Mill Valley

I'm looking for a great babysitter for 2 children. My children are 7 and 9 years old and very well behaved. They may have an activity on wednesday and thursday some weeks that will require you to have a car to take them to and from the activity. Otherwise, I would need someone who can help them to sign onto a computer for math tutoring, oversee their homework being done, and prepare dinner and help with the next day's lunch packing. Some light housekeeping is required.
