Babysitter Needed for my Children

We are looking for a great nanny/sitter for 1 child in Ann Arbor (4. 5-year-old boy). We would prefer a nanny who has their own car, who does not smoke and who has college degree or in the process of obtaining one. The applicant must speak either Cantonese or Mandarin; and should be ready to play fun games that teach our son to speak one of these languages.
