Ask HN: Selling an unfinished or unwanted project?

I currently own two domain names, ios5guide.com and ios5developerguide.com . Frankly I don't have the time to sit down and develop these domains to their full potential. I've had multiple colleagues and developers tell me that they feel the domain value alone is in the 4+ digit range with the upcoming launch of ios5.

So I ask you HN, who/where should I goto handle the sale of these domains and what's the best way to maximize the value?
