Well I have heard around the forums that skinning doesn't give that much of money on high levels, but I can't confirm it. I would suggest you try Herbalism and Alchemy, you could make your own health potions, buffs, and even elemental resistances, they are appreciated in heavy elemental raids. That, if you don't like blacksmithing. Or you could always give Enchanting a try, to enchant your own weapons, although enchantments you can also buy.
