This is the beauty of warcraft, there's a ton of ways to get gold, so you should do the one that you like the most, or hate the least. I bounce around, i did quests for a while, then did heroic grinding, then did pvp grinding and bought gems, then did professions. I think ill get a few more crafters leveled, but nothing on the kind of scale Shodokan is doing.

Good luck, I hope you reach your goal! Maybe be the first to figure out if they up the gold cap?
