Nanny/Mentor Needed For Special Needs Son

Looking for a mentor/sitter for non verbal but highly intelligent special needs son. 9 years old. Special needs experience. Someone to play, teach and socialize. Read to him, someone energetic who will teach him new things, play outside etc. We are looking for someone fun, energetic, patient and creative to work/play with our son. Someone with a bubbly and proactive attitude. If it were up to him he would play on the iPad all day but we want to break him out of that routine. Someone who will play games, teach him socialization, turn taking, some exercise, reading, games, all while teaching him independence and how to "use his words". He uses an iPad to talk. He's very smart, happy and friendly!
