I talked to a few of the people on localbitcoins once a while ago (few weeks?), never actually done any trades but basically scanned their pages for contact info and got in touch with them to discuss bitcoins when I was looking to establish a new and much bigger cashout structure just to hear their opinions, business models etc. Just PM me if you want a few suggestions of who to go to, but you can usually mail them by opening a trade, getting their details, then cancelling and they're pretty open about things actually once you do a few small transactions. Unlike the US version of localbitcoins which I also watch, the UK zone is generally speaking scam-free, anyone with more than 30 good trades are usually solid sellers.
