Hi,
No offence, but if you're making 7k a day from Ores then frankly you must be farming the crap out of Pandaria (Ghost Iron Ore?) *selling* more than 90 stacks a day. At this point I would diversify or risk players reports from Pandaria or from the AH competition or LPC detection/whatever. My actual advice would be to chill out and take it down a notch before you get your first suspension, otherwise diversify and take your account and spend a little time diversifying:
Jewelcrafting:
Prospect the ore if you have a Jewelcrafter that you are interested in playing -otherwise don't diversify and keep selling ores/bars.
Mining routes:
Mix up your Mining routes and try Fel Iron Ore and Adamantite Ore (BC) or Cobalt Ore (WotLK): but check if bars or ores sell at a higher rate... IIRC Fel Iron Bars sell higher than their ore.
Undermine Journal:
Check gathered > mining and see what sells high on your Realm.
Skinning:
A great money maker but takes time to level -though no outlay -and is quite easy to be spotted as a bot if you over work your Skinning farms.
Fishing:
Not such a premium market now, the profits were ridiculously high in 5.0 and 5.1: but again like Skinning this has no outlay and keeps your farmer in Pandaria.
