The way to make money is to have at least one gathering profession…mining, herbalism, or skinning. You sell the raw materials on the auction house…whether ore, herbs, or skins. Some people take two of those three, and do not take one of the crating skills, to maximize income. Later, at high level, it is easier to drop a gathering proffession for a crafting one…and level it up quickly.
You can also make decent coin selling cloth drops at auction. Search to see how much the going rate is, undercut it so your stuff will be first on the list and sure to sell.
