How much do you think you are worth? Are you skilled? Is 3dgs the only Level Design you do know? Do you use other Level Editors besides Wed? A few questions you may ask yourself.
Prices can be determined on the skill you may have. If you need to know what it is worth give me a e-mail over at Level_Designers(at)lddreams.com and I will be happy to answer any questions you may have. I do not plan to hire anyone by the nature of this post. I am just posting I can tell how much it is worth if you are skilled to be a Level Designer.
