I just want to give some props to Palmer over at DesignOutpost. He’s crafted a great site over there. If someone has a design need for a graphic, website, logo, template, flash movie, or similar project, you can post a contest and you’ll have people prepare entries that you review and pick a winner from.
They’ve assembled a talented group of designers. I’ve had two contests there (here, and here). I had great success with the first one, and the 2nd one is still in progress but the initial entry has “winner” written all over it.
So I recommend you visiting Design Outpost to see what they can do for you.
