Nanny Needed For My Children

We are looking for a great babysitter for 1 child in Salt Lake City. We would prefer a babysitter who has their own car and who is CPR certified. Mom is a flight attendant and dad is in medical school, looking for occasional help in the evenings picking up son from daycare and helping him with nighttime routine so dad can stay on campus and study. Schedule would vary, but would be known about 1 month in advance. 2-3 days a week max.
