If you can be bothered with setting up APM and reposting glyphs a couple of days. Restocking them, then Inscription is a pure goldmine. Once you know all glyphs, that'll beat quite a few alchemists profit wise.
It ofcouse matters how many active people you have on your realm who will undercut you. So that's my tip, level one of those. Besides that it'll spare you loads of gold buying glyphs, since you can make them.

Alchemists has always been the most popular proffesion amongst boxers, so that seems like a good pick, Not sure about the second one. Tailor is probably easy. JC could make more profit, slighty annoying to do the JC daily 8 times aswell.(if the item that's needed drops for the whole team, else you have to farm 40 of them)
