Babysitter Needed for my Children

We are looking for a great nanny for 2 children in Pittsburgh. We would prefer someone who could help out with watching the children, keeping them safe & helping with picking them up from daycare. Currently I work a varied schedule requiring closing shifts. Looking for childcare from the hours of 5:30 p.m. - 10 p.m. 1-2 nights a week. We would prefer a nanny who has their own car (valid license) who does not smoke and who is CPR certified(preferred not required). Days needed would be given in advance for each month!
