Part-time Sitter Needed

Looking for an energetic, creative, responsible sitter to help care for and possibly shuttle kids on an as needed basis. We have 8 children and a very busy schedule. Care would be for the 4 youngest kids ages 2, 5, 7, and 9. May occasionally need you to stay a weekend as we have 4 on competitive traveling soccer teams. Days would vary but hours would mainly be late afternoon/evening during the week and vary on the weekends.
