You do NOT want to do enchanting... trust me... it is NOT worth it. With blacksmithing you can mine your resources relatively easily. With enchanting, you have to DISENCHANT all of your components from existing magical items. This means your progress is gated by how many green, blue and purple items you are able to get your hands on. Also, most items have several components they can disenchant to, and varying quantities... all of which are random. I'm at 140 right now, trying to do damage enchants to weapons. These require 1 large glimmering shard per enchant, and it's been a complete PITA to get them. I've lost at least 50g in vendor and AH sales because I have to disenchant every green blue or purple item I come across (that I can't wear myself that is).
Enchanting is the slowest grind and most expensive of the professions (with good reason considering how powerful it makes things)... if blacksmith annoys you, enchanting will infuriate you. If I hadn't dumped so much time into it myself, I would be rethinking my profession.
