Babysitter - Full-time / Part-time

We are looking for an overnight sitter for our 7-month-old baby boy in Washington, DC while we travel out of town for a funeral. Start date would be 9/30 beginning in the afternoon or early evening, and we would be back Thursday night around 7-8 p.m. (so we would need care overnight Wednesday night and all day Thursday). We would prefer a babysitter who has their own car, who does not smoke and who is CPR certified.
