Babysitter - Full-time / Part-time

We have a 34-year-old daughter who is a person that is high-functioning special needs person which means that she speaks, reads/writes, no physical restrictions, etc. but a bit childish in her behavior (she loves Nintendo, Pokemon, Roblock, etc.). We need someone to be her companion, act as a friend to talk and play with. Shes good-natured with a good sense of humor. She loves kids so stories about kids in school would be great. We need someone for a few hours on Sundays (3-5 hours, pretty flexible).
