Is this - or another forum - appropriate for finding someone versed in X code and apple script - to do a paid job?
You could try at stackoverflow, they have an special segment for jobs (http://careers.stackoverflow.com).
But before you do: Write better job opening than you did here. Otherwise you won’t find any, people (including me) don’t reply on an “AppleScript and Xcode” vacancy description. It doesn’t say much about the job but does say a lot about the person who wants to hire you.
