Are you looking for one person to do the Mac, PC, and Linux desktop clients? That would explain why you haven't found anyone yet. People tend to become good at developing for only one of those platforms. I can (and do) both web and Mac programming, but don't live near Seattle. Of the 2, I prefer Mac programming. I can't speak for Windows or Linux client development, but most of the Mac developers I know are running (or want to start running) their own indie Mac software shops. So you might want to find some quality Mac software contractors (I know a few).
