Inscription is very easy to make a few thousand on and is really cheap to level. His question was merely what the quickest way to 4k gold is, and inscription can net you a good portion of that while leveling it up. It's not going to be as good as JC, however JC is much more expensive to level and will take a while to build up cuts that you can make money off of. Plus, I am not sure about your servers, but the gem market on mine has pretty much collapsed, and the margins are so thin that many people are backing out. The profits are low enough that transmuting gems isn't really worth it, and xmuting truegold has been a loss for months. Speaking from the pov of someone who has all of the crafting professions at max level, the only one I'm still getting consistent gold from is inscription...though that might be due to my server, so ymmv.
You'd also be surprised how well glyphs sell even though you only need to learn them once. They also cost next to nothing to produce.
