Complete a Mac OS app

I have an app that works now but needs some UI work. The app was modified from an apple sample app. I added some fields and labels in interface builder but can't get them to link to my code. I need someone to take my code and fix it so that I can take input from the window buttons and text fields and output to labels there. All the logic of what the app does I have handled and can modify later. I am a iOS developer but am busy an another project and don't have time to figure this one out. My estimate is that a good mac OS coder should be able to do this within a 2-4 hours. If this were an iOS app I could do it under 4 hours for sure. I will supply all the code and show you what I think is wrong... which is that it has an app delegate and a view but doesn't have a view controller. So that's probably the extent of what I need.
