Are they a holy/political order? (3)
A former (or current) military/mercenary unit? (4)
All these groups would have different sorts of names, for example:
1) The Stone Lions, The Heroes of Winter Ridge, The Black Foxes
2) The Pathbeaters, Macguffin's Recovery Service (you can't have that one its mine), Acquisitions Inc.
3) The Order of the White Rose, The Brotherhood of Vandhalia, The Purple Dragon Knights
4) The Last Chance Brigade, The 4th Antari Rangers, Hagdren's Horde
There are lots of other possibilities. Give the guild a history and a name will come naturally.
Edit: To the people who ninjah'd me. GET OUT OF MY HEAD!!
