Companion (act As A Friend) Needed For A Girl

We need a person to be a companion (friend) for our daughter. Our daughter has special needs - she's talking well, has a great sense of humor and is smart and pleasant but still childish. She's interested in video games and super heroes. She is also very interested in medicine (playing doctor or nurse). We need someone with patience who likes to play and listen in these areas. We need someone for both Saturday and Sunday. Saturday is flexible (can start at any time after 10 a.m. for 3 hours) and Sunday needs to start at 1 p.m. until 4 or 5 p.m. Should have her own transportation and doesn't smoke.
