Nanny/Evening Assistance Needed For 2 Children In Knoxville.

We are looking for someone to help with 2 children in Knoxville. We would prefer someone who could help out with light housekeeping. We would prefer a nanny who does not smoke and who is comfortable with pets. We basically are looking for assistance between 6-9 p.m. on weeknights, mostly as an extra set of hands to help with educational/beneficial play with the kids and help getting them to sleep. Dad is a busy professional and mom is overwhelmed.
