What is the maximum you would pay for a design?

I'm really curious to see how much designers could make from just one person.

This includes a small 1 page design to a huge 100 page design.

Maximum I could see paying for a design for myself would be for my hosting site (hostwish.net) and that would be $1k. Right now that isn't feasible so I am having someone do it for a discounted price.
Depends on a number of factors, depends on what type of design it was. Whether it was a thumbnail, logo, banner, or website design. The maximum I could see myself paying for a website design is 100 USD$ if it the developer ticked all the boxes. On the otherhand, I would pay less if there wasn't much effort put into the design.
