Babysitter Needed For 3 Children In Milwaukee.

We are looking for a great babysitter for 3 children in Milwaukee( one is 17, so not much to do but will need a ride home from school). We would prefer someone who could help out with light housekeeping and homework help. We would prefer a babysitter who has their own car, who does not smoke, who is comfortable with pets, who is CPR certified and who has college degree.
