Babysitter Needed for my Children

We are seeking a reliable sitter for our two children in Miami, specifically near the Design District. Our primary need is for evening and nighttime assistance after the children are asleep. Occasionally, we may require daytime help on weekends. Our son is 2. 5 years old, and our daughter is 8 months old. We would prefer someone who does not smoke, is CPR certified, and has their own transportation. Both children are well-behaved and would require minimal supervision since they will be sleeping most of the time.
