Childcare Needed

Looking for a sitter for my 5-year-old special needs son. 4 days during the work week from 2. 5-3 hours, days inconsistent, time would be 2-4:30/5. Sometimes maybe could be more hours or extra day here and there. I need someone patient, reliable, responsive, who has experience with autistic children and a reliable car. Would prefer someone who could help out with light housekeeping. We would prefer a nanny who is comfortable with pets and who is CPR certified. He is not potty trained and he is in need of constant attention, he has no awareness to danger. He is a very lovable sweet boy!!
