Well, if I wanted to start a CTR service or whatever I might have bought it - but I am not.
I'd personally just make it a homepage where people could contact you if they wanted to buy it.
You might never sell it, or you might do. It is better to just let it sit and not put any effort into it.
Get 2+ interested people and see if you can make it a bidding war, this is usually a good way to ramp up the price of everything really.
Good luck!
