Babysitter Needed for my Children

Looking for an occasional sitter who can pick up my 5-year-old from school (within walking distance from my home) and watch the children on days I have work meetings. Will need someone Wednesday 10/7 from 2 p.m. through no later than 6:30 p.m. , but hope to create a relationship with someone who can help out in the afternoons as needed. Primary concern will be my 5-year-old, however I also have two middle school students age 11 who will be home from the bus around 4:30.
