Babysitter

We are lookin for a babysitter/nanny for 2-3 days a week 8:00-1:00. Days may vary but I can set specific days if needed. I work from home some days and others I am gone. My son is 4 years old and goes to school in the afternoon. Bus picks him up at the house 12:30-12:45. We would prefer someone who has their own car, who does not smoke, who is comfortable with pets and who is CPR certified.
