Babysitter - Full-time / Part-time

My husband and I both work late from home on Mondays and Tuesdays. We will take care of dinner, bath, and putting baby to bed, but we need someone to be available in the 7:00-8:00 p.m. window in case the baby wakes up to rock him and soothe him back to sleep. Arrival to our home would be no later than 6:45 and departure would be around 8:15 p.m. Babysitter is welcome to do their own homework, read, etc. while watching baby on monitor. Both parents home and available for emergencies. We would prefer a babysitter who has their own car, who does not smoke and who is CPR certified.
