Childcare Needed

I am looking for a great nanny/babysitter for 2 children in Knoxville. I would prefer someone who could help out with light housekeeping and homework help. I require a babysitter/nanny who has their own car, who does not smoke and who is comfortable with pets. This would start the week of august the 10th, and go through the school year. It is every other week (not weekly)
