Sitter Job in Montgomery, Minnesota

I am looking for a summer nanny/babysitter for my two girls ages 8 and 5. They have out grown the home daycare lifestyle and I wanted to let them experience summer as a child should. Preferably a high school student or college student that is active and can keep up with two little girls that like to ride bikes, go swimming, play at parks etc. The hours would be M-F, 7:00am - 5:30pm. This person should have a valid drivers license and your own car.
