Part Time Care for ASD Child

We are looking for part time care for my almost 6 year old son. He has been diagnosed with autism and cerebral palsy. He is non-verbal and not yet toilet trained. He is pretty self entertaining with a wide variety of toys but needs help getting them to the right settings, etc. He can get around the house by himself (up and down stairs). I or my wife also work from home frequently and would often be around to help if needed, it's just a bit too much to balance watching him and getting work done throughout the day.

We have family members that help watch him pretty often but during the summer when he is out of school, we are looking for extra help. Additionally, even when school starts back, it would be great to have another sitter for him available for whatever occasion may come up. Days and hours are flexible. Pay is negotiable.
