Mandarin-speaking Nanny Needed For July/Aug

We are looking for someone who is mandarin-speaking who can care for our 4-year-old roughly from the hours of 9a-4p Mon-Fri July 1st through August 15th. Spanish-speaking is a bonus but not required. We are a multi-racial, multi-lingual, and very liberal household. Our son, Leo, is an energetic 4 yo fluent in Mandarin, Spanish, and English but we are really hoping to support his Mandarin learning during the summer. We don't expect you to teach, but are looking for someone to hang out with him and take him on adventures this summer!
