Nanny Needed - Full-time / Part-time

My sister and I are visiting Chicago to see a show and are looking for a dependable babysitter for one evening for our children. There will be 6 children total, though 2 are preteens and fairly independent. The evening will be simple and relaxed pizza, a movie night, and bedtime for the younger kids. We would love to find someone kind and trustworthy to help make the night easy and fun for everyone!
