Sad truth with bitcointalk is that we often get carders that get in the forum one time only just to cash out. There are some trusted vendors but you gotta hunt them down on your own lol..
Anyway, here's a guy that handled US orders and quite reputable too

unfortunately this weakness in bitcointalk is also one of its greatest strengths... its rare to find such an open place on the clearweb
though i have been scammed a couple times now by people i had met here.. i've also met some really great ones too
