Childcare Needed - Full-time / Part-time

We are looking for a babysitter for occasional date nights or afternoons which will almost always be on Saturdays. The first date we will need a sitter for is July 26. We have a 4-year-old and 2-year-old who are truly delightful kiddos! Our ideal candidate is college educated (or currently in college) and has prior experience with caring for young kids. Our only non-negotiable requirement is that the babysitter is a Christian and she regularly attends a local church.
