Babysitter Needed for my Children - Full-time / Part-time

We are looking for a great babysitter for my children in Castle Rock. We would prefer a babysitter who has their own car, who does not smoke and who is CPR certified. The 2 younger boys are with me on 2-2-3 and older children are in full time school. So only the 4-year-old for most of the time. Children will need to be taken and picked up for school.
