If you have a warlock cast 'Detect invisibility' on you, you can see Lorderon Citizens on your way in to Undercity. They are lvl 15, and drop linen, and some copper. It'd be a good lowbie lvling spot if you could get detect invisibility on you at that lvl :/

This also works for the people in Darrowshire and on that island Scholo is on, only they are lvl 55ish, not 15.

If that doesn't work and you need gold quick, I recommend The MMORPG Exchange WoW Gold. They deliver quickly and are cheap! I usually receive my gold within 20 minutes. They're my secret weapon, I highly recommend them!
