Babysitter Needed for my Children

We are currently looking for a nanny to help with taking care of our two 10 years old kids basically on Saturday & Sunday afternoons (3-6pm). Also, help with morning transportation form January till June (3 days a week/8-10am) is needed if available. Experience with autism is preferable for our son. Tasks will include some light house keeping (help with dishes, vacuuming, laundry.. etc). Help with transportation for other activities might be needed occasionally. 38-40/hr (total 12-15 hrs/week)
