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

We are looking for a baby sitter for 2 children in West Palm Beach. We would prefer a nanny who has their own car, who does not smoke, who is willing to drive children and who is CPR certified. The dates and times would be flexible. We are in need of a sitter for date night. I travel for work approximately once a month, sometimes every couple of months. During those times, we are looking for someone who can pick our children up from school and assist with their bedtime routine.
