If ya just want to make massive money, do mining/skinning, with these as your two prime professions. You will be collecting alot of materials, and selling them off at the AH (AuctionHouse). As I am doing only Tailor/Skinning, I have pulled off making over +500g, not to shaby, huh? Try hunting down beasts primely, good beast materials, such as furs, bones, meat, hair, etc, which sell to NPC vendors real well. But, with mining/skinning, you'd be making alot of money, but nothing sufficient to make for yourself. Humanoids tend to be good as well, money/cloth drops, but I prefer beasts to make a fortune with my time.
