Well like a smart little botter, 3 accounts farming ore/Herbs all day, i have a Jewlcrafter, 2x Alchemist, and a private buyer for the Ore, @ 50g/stack, AH prices are still 100g/stack but sell privately to avoid flooding the market too much.
I make Random Gems , such as Brilliant Infenal Ruby something that will fly off the AH put half the ore up, and put some uncut gems that way I'm not posting 100 Stacks of ore per account.
Basically,
1)Accounts 1,2,3 Farm All night
2)Send Half to my JC to prospect
3)Post 20-30 Stacks on AH
4)Send 40-100 Stacks to private Buyer
5)???
6)Profit
I am still able to make around 50k a week like this.
