Nanny Needed For My Children

I am looking for a babysitter starting in September for my two children, ages 7 and 1. The position would be part-time. The hours needed are from approximately 1:00 p.m. to 5:00 or 6:00 p.m. Responsibilities would include caring for our 1-year-old daughter and picking up our 2nd grader from the bus stop, which is located at the corner of our block. Light housekeeping like dishes and preparing snacks for the kids until we reach home would be helpful.
