how to level up crafting professions quickly?

At 50 you get 3 of the scripts for each job by doing a quest, and they give +150% exp up to 300k gained, 20 minute buff. The problem with them is that it's only 20 minutes, and you need to crank out about 50 recipes in that time at that range to get the full benefit. I've been using them with quick synthesis on lumber and nugget and such.

edit - also for the daily GC turn-ins, they give about the same exp as a leve, HQ gives double, a star next to it means double, and HQ on a star gives quadruple
