I don't know of any resource like that since the level of the craft and dLevel are both factors. I usually over gather and aim for amounts relative to leve turn ins since those are much more significant sources of experience. Also, leveling all the crafting classes together might not be the most efficient way to do it. For every crafting class you get to 50 leveling all the others becomes easier. Weaver and Carpenter are especially useful, and culinarian to 37.
