Any professional UI designers out there?

We're boot-strapping a brand new startup, which is SaaS. Our success will depend a lot on the visual look and user interface. While we have a pretty creative contractors on board, we're considering bringing in one as a co-founder. It's a weighted decision. The UI and design are going to be pretty essential parts of our products. So if there are any great and creative people around who'd like to join a fresh startup, I'd be more than happy to talk to you.
