Okay. So, I did a search for Artisan's marks and found nothing. But here it goes.
Heres a few requirements.
1. Extra time or money to farm/buy mats
2. Extra profession slot. 1/3
What I found out you can do is, at least at lower levels (only level 16 atm) is train in a profession, do the daily quest for the profession and then get the artisan marks for it. After that, untrain the profession, train in a different profession and do that daily quest. Each give you 3 Artisan Marks. Continue to do that through each profession.
