Afterschool driver/nanny needed for 2 kids, ideally Chinese (belmont)

We're looking for someone to help us pickup our kids, and ideally help them with their homework.
If you can speak Mandarin Chinese, that'd be ideal to help with Chinese homework.
My son's in 5th grade at Orion Mandarin Immersion Elementary school in Redwood City, and daughter is in 7th at Nesbit Middle School in Belmont.
We live in Belmont, in the Hallmark area.
Schedule for pickups is Mon/Tues/Wed/Fri at 2:40, Thurs at 1:40.
On some days, we'll need you to drop off kids to after school activities.
Looking for responsible driver, and use either your car or ours.
Perfect job for a college student or high school senior, or retired adult, or au pair/nanny looking for a few extra hours.
thanks!
