WTB Rusted Proto Drake

I just want to buy the Rusted Proto Drake off of Ulduar 10 HM. I have 6/13 achieve and was wondering how much it would cost? All I have right now is just 8k. I can probably get 10k by sunday if 8k is too low ballin.

My in-game name is Corose, Gnome Rogue.

EDIT: just in-case there is a gear check I am a 5838 combat rogue. I'm most likely logged out in my pvp gear so just www.wow-heroes.com my rogue.

which achievements do u have? we currently have a min charge of 14k and 5k for algalon alone. 3k for just one light and 5k for firefighter.

I have the first four bosses, steelbreaker, and crazy cat lady. If the price still stands at 14k then I guess I'll just have to wait till next week once I farm more gold >.<

yea it still stands at 14k because u dont really have any of the harder achievements to get
