Domains for sale

I have a few domains I no longer need and are for sale, though I’ve never sold domains before so not sure how to do it. Any webmasters here former or present with experience in this field, how do I go about putting them up for market, and how do people find them to know they’re for sale?

I have (don’t worry not spamming, these are simply domain names, no hosting packages with them, so they aren’t actual websites. I just own the domain names and want rid)

londongroomers.co.uk (this one will bring in a couple of grand at least. Pet grooming is a big business in London and I’m sure a grooming shop in London will lap it up)

installphpbbmods.co.uk (I used to install phpBB2 mods for people for a small fee, but now v2 is obsolete I cancelled the hosting and no longer need the domain, will try ridding this for as cheap as possible)

friendlychatforums.co.uk
friendly-forums.co.uk
friendly-chat.co.uk
friendlychatsites.com (was gonna setup a directory of online communities I deemed friendly/safe/well moderated, but just don’t have the time these days to go around finding & reviewing, so again, cancelled hosting and want rid)

Any info/tips/help on selling them would be great. I’ve Googled “sell domain names” but I have no blooming idea what I’m doing. I’ve come across Sedo where it looks like an auction site for domains but looks quite complicated and not sure how it works.

Heck with the exception of londongroomers & friendlychatforums I’ll give the others away for free to willing recipients!
