Babysitter Needed - Full-time / Part-time

Hello! I need someone to pick-up my son up from school at 3:30 p.m. and watch him until my husband or my myself get home from work. The earliest one of us will arrive is 7:30 p.m. 3x/week and 5:30 p.m. 2x/week. Thus, we would need someone for a least 16-hour/week. This position would need to start the first week of September.
