Right now my shamans are Lv. 50 and I sit at about 1.5k at least if not more (alot of AH stuff on atm).

All I do is run instances, and loot EVERYTHING. Even gray weapons give you one gold. I have my enchanter to melt the drops and I sell the green with good stats on armor types. I believe I'll have enough to buy my epic mounts by the time I get to 60 and flying by the time I get to 70 for sure.
