I just recently got done updating all of the guides on my site for every profession (excluding inscription, haven't gotten around to that one yet. Sorry! =( ). Each guide gives you the fastest possible way to level your profession (and cheapest!). Of course even when using the guide you should expect to spend quite a bit of gold on your profession, especially this early in the expansion but I hope that these guides help someone out! =)
