Childrens web site with advanced functionality

Function of the site: We will have a few contests each year for kids. For example, we will have shirt month and kids will submit pictures of their dream shirt. We will upload the best images to the site and have a voting period where users ote for the winner. We will then work with a designer to make the idea a reatlity. We will have other contests such as sock month/pants moth etc. The clothes will also be made for kids who are sensitive to tags/seams etc phase 1 or childrens web site --- initially be very simple.
