I agree with this. There should be a simple "Request Crafting" where they right click you and (if you agree) they get to use the crafting log at YOUR level (so they can see all recipes). They choose what to craft/HQ etc just as if they had level 50 or whatever. The difference I would like to see is:
A) When they hit "Craft" you get a popup "Start Crafting?" after which you assume control and craft away.
B) A "Tip" area (like melding) where you can get guaranteed pay. Perhaps 2 slots (1 for success 1 for just trying?) You can see this before agreeing to craft.
C) Items crafted (or failed mats) go directly to the paying customer. You still get your tip (at least the "just for trying" part)

On top of that there should be a request for repairs as well. It's silly to expect everyone to level every DoH to 50 for optimal repairs, but not so much to expect an alliance of 8+ to have odd-jobs to be able to repair through lengthy dungeons/instances.
