I'm not sure exactly what you mean by unique, but here are three of my already existing tracks that might be worth looking at. You could use any one of them as long as I'm credited for them as John Stuart. If you're looking for something more specific, I can definitely give anything you might want a shot, but as mentioned in an earlier post, I'm right in the middle of a fairly large project for someone important, so I may not be able to have it done as quickly as normal, but I'm willing to try anything.
