Sitter Needed For Child With Special Needs

I am looking for a great nanny or sitter for 1 child in Columbus. I would prefer a nanny who has their own car, who does not smoke and who is CPR certified. Child is autistic and you would need to be comfortable with a child who is also non verbal. so you will have that patience in order to communicate with her. Person would have to have experience working with children who are special needs.
