if you do a search for "dating" you'll find plenty of sites. most you pay for, a few you don't. you get what you pay for, so the free ones are generally less "classy" than the pricey ones.
By the looks of it, you aren't keen to register into the dating sites, which you'd find dime a dozen. I guess social networking sites are a better option. A new one is TabUp.com. My brother uses it and is pretty regular. Hope you find someone special soon.
match.com Have advertised on TV
midsummers eve and dating direct are worth a go.
Ivory towers is more exclusive and more expensive.
But you really are better off trying a dating agency which is local and where you are met personally and have introductions. Dating agencies on line are cheap and used by those who are not always genuine.
Good luck.........x
