Can you describe the nature of the app. or any general description?

crowdspring.com tends to have a more 'creative' bunch than all the other outsourcing shops. post up a project! they just changed their policy that the buyer is not required to select a winning design. You can walk away if you don't like the submissions, and the cS will award the prize out of their pocket.

..and then there's always me. I don't have formal training in UI, but I've been at it for a while. @faramarzhashemi
