Babysitter - Full-time / Part-time

We have 3 beautiful and active girls - ages 1, 3, and 5. They are at preschool/kindergarten from 9-5. We're looking for help in the afternoons/evenings during the week and occasional weekends. My husband and I both travel for work and looking for additional help around the house. Right now we do not have set hours that are needed but willing to work with a desired or flexible schedule. We can offer 15-20hrs per week
