There is a guy in our guild who is doing really well at making gold. He has just hit 80, and has (so far) no tradeskills.
I have an inscriptionist, and make glyphs (have all the recipees). However, there are two parts to this that I dont enjoy; Milling inks and gathering mail. My guildy buys the herbs, gets them milled, and sends me the ink of the sea (which I pay for). I then turn the inks into glyphs, which he then posts for me and I pay him a cut for that too.
Finally, he gathers epic gems from a stable of alchemists, for which I pay a set price. By doing the running around and providing them with the mats, he gives them a small cut, and adds another large cut for himself before mailing the gems to me. I also would not be surprised to find him scanning the AH for gems that I am after.
By doing this, inside a fortnight - starting with as a (roughly) level 65 toon, he earnt nearly 8k in gold. Yes, If I had the time I could have been doing these things too, but I don't enjoy that part of the game, and he does. And he is really enjoying making gold.
I won't hire PL/PH (aka Travis was at least funny) - I've been pressed by commenters and even the CEO of Pandemic Horde to hire PL instead of supporting MoA (read them from the bottom up): Well, Travis was...
