One thing that I did to level my chanting up to artisan level on my pally alt was to spam a skillable chant (orange or yellow) on the same armor piece or weapon until I either reach the desired level for the next recipe, or run out of mats. Unfortunately you waste the chant and the only positive outcome is a skillup, however I believe that chanting recipes of lower lvl than 300 are only there for you to waste in order to lvl your chanting, not for sale since no one really wants them.
