If you killed the last boss already, you cannot get another quest item. So its 1 per week.
Update:
After you complete the quest you wont get any teleport spells on your spellbook as many of you (including me) thought. Instead you will be able to open the door that leads to blackhand. There are two packs of mobs right before the door, each pack has a stone in front of it. If you click either one of these the door to blackhand will open.Edit:
If you complete the Quest on Heroic, you'll be able to click on the normal one as well. If you complete on Mythic, you'll be able to click on all 3 difficulties

If you have forgotten where to hand in the quest, the guy is hidden behind a load of boxes and crates to the right of the Iron Maidens.
If you've just completed the quest and wondered "what now? how do I skip to Blackhand?"
There are two large Blackrock Artifacts behind the trash packs in the main room. Click on either and the door leading to the Blackhand encounter will open.

Description
<Goraluk sighs with... relief? ...or perhaps regret?> Once I walked these halls with pride, holding my head high as an orc of the Blackrock clan. But this is a wrong path. Our hammers were meant to craft axes, swords... not these machines from the stranger's whispers. The Warlord will not be swayed, but by force. If you can retrieve essences from the Foundry's most powerful guardians, I can craft for you a sigil that will permit direct access to Blackhand's Crucible.
