- Boxing dailies (~12g * 25 * 5 = 1500g/day)
- Argent Pets (40 seals per pet, ~1.5-2k per pet, 5*5=25 seals/day = ~900-1200g/day average)
- 2 tailors 1 JC, ~90g per cloth and gem = 4+2+2 = 8*90g/4days = ~180g/day
- Heroics. 1 abyss (~125g), 4-6 dream shards (15*5=~75g), 8g/essence and 3.5g/dust gets me about 50g from green de's, frostweave is about 10g/stack, coins/vendor trash, 10 badges = scarlet ruby = ~70g... I think the average heroic run nets close to 500g.

Those are things any boxer can do to get a ton of cash. I also play the AH with buy low/sell high and luck out from time to time. When the announcement came out about titanium ore being prospectable for epic gems in 3.2, I managed to immediately snag almost 50 stacks worth at 2-3g per ore. I've sold about 10 stacks at 10g per ore already :).
