Money was never a problem for me leveling. I went 1-60 with a team of 4 doing quests and had enough to buy my epic land mounts when I hit 60. The only profession I sold stuff with was Mining. I have an herber, skinner, and enchanter but I used all those to skill up with. Just the vendoring of BoP quest items on your non-enchanters should be more than enough to train your spells with some left over.

Unless you're RAF'ing... then you better pick up all gathering and no production professions and play the AH .
