I’ve found quite a few themes for WordPress on www.alexking.org. One thing, make sure to check the themes in all browsers. There where a few great themes that worked well in FireFox, but in I.E. they where really screwy. (Mostly CSS issues.)

You may want to think about just building your own template. Like we did on www.totallyhotmen.com. They are pretty easy to design and set up as long as you don’t mess up the php codes.
