Yes, we did have some promising candidates, but that was almost a year ago. We already hired one guy to be a full time SketchUp developer, but unfortunately he quit after releasing one new SketchUp plugin version. As Ondra said, the current situation on the local job market is far from ideal and skilled labour is in extremely short supply. And to be honest, developing a SketchUp plugin is not the most sexy thing you can do as a skilled programmer, so I can image people wouldn't want to quit their current jobs just to do that.
