I've read the question "how to tame when you've finished the quest" twice and no answer... I'll answer. You're going to need a player that has the quest, really. You need the meat, and without the quest, no meat for you. I'm not sure, but it might be on AH too. You can check.

Good luck taming him, he's wonderful!
