Babysitter Needed for my Children

I'm looking for a great nanny for 2 children. We do have a total of 4 children but the older 2 are gone before you start the day and dont come home until after you leave. There is some slight overlap from time to time and on days without school. Our 3yo goes to preschool 5 days a week from 9 a.m. to 1 p.m. Some light tidying up and meal prep for the little one would be part of our caregiver's responsibilities.
