You'd have a whole lot more luck finding a story, if you posted this in the Searching for a Story thread. There's even a special thread, just for TV: http://www2.adult-fanfiction.org/forum/index.php/forum/646-television/
Unfortunately there doesn't seem to be a specific category for Justified yet, but I'm sure there are other Justified fans out there, who have posted stories, and can help you out, if you post in the right section.
(sorry, DG, )
