Nanny Needed For My Children

We are looking for a great babysitter for me and my sister's children in Farmington Hills, MI. She's visiting from out of state. The hourly rate would be higher while she is visiting with her 3 children and adjusted to a lower hourly rate when she leaves town. She visits multiple times a year. We would prefer someone who could help with light housekeeping. We would prefer a babysitter who has their own car, who does not smoke and who is CPR certified.
