How much should a shading artist be paid?

I have a question: How much should a 3D artist be paid for doing work like materials and shaders?

First it depends where on Planet Earth you live…

A percentage of profits if it’s your first gig,

and all else depends on your skill level.

Photo real + really fast = top dollar.

Crappy + slow = none at all.

Where do you rate?

Example shots of materials?

@Vandorious Hehe, maybe I should have been more specific with my location.>:3 I live in the USA.
@BluePrintRandom Yep, first gig. I can make photorealistic shaders, but I’m not the fastest at it. I’d say I’m in the photo real + fast category though. I don’t have any examples of my shaders, I suppose I should get that set up.
