Childcare Needed - Full-time / Part-time

We are looking for a great babysitter for 2 children in New York. We would prefer someone who could help out with light housekeeping. We would prefer a babysitter who does not smoke and who is CPR certified. I need someone who is reliable and keep communication with me. We all know kids say the darnest things, sometimes my kids may speak without thinking. They are really sweet and friendly.
