Babysitter - Full-time / Part-time

We are looking for a great babysitter for 1 child in Saint Louis. We would prefer a babysitter who has their own car, who does not smoke, who is comfortable with pets, who is CPR certified and who has college degree. I am ideally looking for a sitter for Monday and Tuesday full days during the summer only. I also would like to have someone in the afternoons during the school year to stay with my daughter for a couple hours till I get home.
