Babysitter Needed for my Children - Full-time / Part-time

We are looking for a sitter for our 3 children. The primary need is for the school year but also flexible when the need arises for other days. Due to me and my husbands work schedules, we need someone to put our children on the school bus each morning. I have to be at work by 8:15 and my husband leaves a few hours earlier than me. Our kids get on their bus at 7:40 and 8:20. We would prefer someone who has their own car, who is comfortable with pets as we have a dog and who is CPR certified.
