Domainers are the toughest industry to try and sell a domain too, i would concentrate on other endusers, domainers generally make up there own words and do it quiete well, and get the dotcom
there is no value in this name with us ext , with the dotcom it would have some value. Dot US domains arent anything compared to dot.de dot de have a big following dot.us is pretty much ignored
good luck hope i am wrong
