Other names have wide appeal. There are forums (DomainState DNForum) for example where you can sell the names but often these are often frequented by resellers so the price achieved and the speed of sale reflects this.
Most of the resellers at those forums hope for private email enquiries like yours :)
There are specialist domain selling sites like Sedo and Afternic, but you need to advertise your name on their boards and it may take a while before the buyer at the right price is found.
Some big Auction Sites like Ebay sell quite a few domains but there is often a lot of junk / unrealistic prices on them so serious buyers do not go there that often unless they have heard a specific name is for sale there.
We don't sell names but we get several enquiries to purchase them each month sometimes several a week.
The enquiries are often from anomymous web based email like yahoo or msn and range usually from a $yyy to $yyyy.
