Childcare Needed

We are looking for a great babysitter for 2 children in Columbia. 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. The eldest child will only need dinner made for her. She is very comfortable with helping with her brother. She will help with bedtime if my husband doesn't make it home by bedtime.
