You'd probably do better with one of the online forums. I think you need to have a minimum post count (number of comments) of 25 or greater to post anything for sale on Watch Talk Forums' Sales Forum, but there are other online venues (e.g., Ebay) where you can sell it auction style by opening an Ebay account and registering as a seller. That way, you can set a minimum (or reserve price) that would be the lowest price acceptable to you, and let it run for certain lengths of time (e.g. "one week" or "thirty days"). That would probably be your best bet.
