Caregiver Needed for SEVERE Autistic Adult

In need of a caregiver for our 18 year old severe, nonverbal, autistic son. We are looking for help after school 3:30-7:30 and Saturdays 10-4 total hours between 16-25 needed but more hours available in summer months. He has some behavioral issues such as touching/pulling hair and touching inappropriately and OCD. He requires supervision at all times. He likes going into the community but also staying at home. He needs someone to help him through his day such as activities, showering, cooking. Experience working with severe autistic individuals is ideal. Thank you for your consideration.
