Babysitter Needed for my Children

We are looking for someone to be a babysitter/nanny for our children. We need someone available at a moments notice to assist in either picking up our children from school (sometimes it can be a late minute notice - as in notified within two hours of when pickup needs to happen), and we would need this person to be available for evening care at times. We would prefer a nanny who has their own car, who does not smoke, who is CPR certified and who has college degree or is working towards one. We would also prefer someone who is a Christian because we want our children to continue being exposed to the love of Jesus and all those Sunday school things.
