Childcare Needed - Full-time / Part-time

I'm looking for a great babysitter for 2 children. Please be comfortable with pets, as we have a dog. They are twin boys, one of them does have autism. We are looking for someone who has experience with autism. He would get home from school at around 3 p.m. so it would just be him until his brother comes home at around 4:15. It would mainly just be playing with him until I or my husband get home from work around 5.
