Sitter Job in Palo Alto, California

We are a family of four living in Palo Alto. My husband and I both work full-time. We have two young boys in third grade and In sixth grade. They both attend Chinese school. We are looking for a Mandarin speaking nanny or babysitter who can speak to them exclusively in Mandarin and also help them to review their Chinese lessons for the week. They are very playful boys who enjoy art, crafts, games. If they do have activities, we would love help dropping them off and picking them up. Some light housework and simple dinner would be truly appreciated. We are looking for someone for Tuesdays and Thursdays only starting in mid August. There is the possibility of another Chinese family on our same street who may also need a nanny/babysitter. Thank you in advance for your consideration.
