@d21lewis, I think the guys name is Ghost Dog 360.... something like that. If you go to crucible and browse users he's in the top ones. He has maps specifically made for grinding gold. I recommend you do the 30,000 one, that's the map name. I takes about 10 minutes and if you don't die you'll get 30k gold. You only need 190,000 to unlock all crucible content so as you can see it doesn't take that long.
If I was wrong about the name just look at the achievement guides on TA, that's where I got that from but its very doable.
