You're going to find this VERY hard to find.
For a start, do you have any designs that you need to work from? Do you have any idea of how the site is supposed to look?
If you can't do it yourself, you have two choices. Either download a theme from the themes section here and make any modifications yourself. There's a few that are pretty good, so something should be able to fit your needs. The other choice is do a web search for something like "free wordpress theme generator" and just see what results you can find.
Depending on the requirements of your project, you're going to find it hard to find something that will eactly fit the look and feel that you are going to want. Any time that someone has a need for something "unique" it normally means that you'll need to learn how to build themes yourself.
