Childcare Needed - Full-time / Part-time

We are looking for a great babysitter for my children in Aurora. We would prefer someone who could help out with light housekeeping. We would prefer a babysitter who has their own car, who does not smoke, who is comfortable with pets and who is CPR certified. I will be home some of the days doing yard work, and will be away from home other days. Looking for 2-3 days a week and I am flexible with those days. Have had neighbor girls who have babysat the last 7 years, but they have more full time jobs this summer.
