Looking for Cocoa UI input

I have a commercial Cocoa app built with Xojo that has a decent but uninspired UI. I’d like to spiff it up with more modern icons and perhaps some nice Cocoa touches, but that’s not my forte. I’ve seen some terrific examples of Cocoa UI’s built with Xojo, so I’m posting to ask if anyone would be interested in working with me to improve it. There would be compensation (the amount depending on the amount of effort required). If you have talent in this area and are interested, please respond by opening a private channel here or writing directly to jda at his.com. Thanks.
