Apameda, he wasn't talking about enchanting anything, just disenchanting and selling all the mats.
That's actually a pretty good idea, around level 40 most of hte items I get vendor for around 50s, but I can get 70+s from the enchanting mats at the AH. And occassionally you'll get lucky and get a 3g mat for a 20s item :P
Other than that, yea, Mining/Skinning would probably be best and easiest. So far the only thing I've sold as Tailor/Enchanter are bags and a couple of enchants (I am behind in keeping my levels up, though), so I wouldn't suggest that.
