To those thinking about dropping a profession and picking up enchanting to do this, I thought I'd let you know my experiences getting enchanting to 225. Now keep in mind your server and situation may very.
I was a 40 rogue (gained 2 levels since) I ran Deadmines 5 times and dis-enchanted absolutely every green and blue item I got. This put me at 48 enchanting, some of the stuff you will have to hold on to till you hit 25 enchanting (which you'll probably hit on your second run, maybe start of 3rd). I've read that you can hit 50 solely through dis-enchanting but not higher. I don't know if that is the case or not. With all items I got from dis-enchanting + about 60g, I was able to hit 225 enchanting.
I still have 14 small glimmering shards that I got from dis-enchanting some of the blues in Deadmines, and some other random dusts. On my server that will make me back some of that 60g.
All of this took me about 7 hours spread over the weekend, remember I was 40 at the time, you could do this faster I'm sure, and if you plan it out better you can cut more time.
So, if you are at a level where soloing BRD is possible, you'll make up the money it takes to get enchanting to 225 in an hour more than likely.
I'm broke now though lol, so that's as far as I'll be taking enchanting for now.
