Childcare Needed - Now Hiring

We are looking for a great nanny/babysitter for 2 children in Chicago. We need consistent full day help from September to November/December and then childcare on as needed basis. We prefer someone who could help with light housekeeping and a non-smoker. Also would like someone who is comfortable with pets (our dog is non-hypoallergenic) and who is CPR certified. Thank you!
