Just an opinion, what do you think:
For the same reason Marketing questions should be toned down on GD:SE, I don't see why the "pricing" questions should be mixed with the Graphic Design Stack.
They're very close to critique questions and at this point, might as well accept printing quote questions.
Etc. (so many!)
The Freelancing Stack has a lot of these questions already but it's mainly used by coders and dev. These guys need some designer friends; the GD:SE pricing questions should be sent there.
