Check your local frame-shops...they always have samples of the work they do and for just a little bit of your time, you can bring the documents in and they would be more than happy to sit down and work up something very nice and within your budget-range.
We have a few "show posters" that we've had framed for our place...chrome, wood and just plain black plastic. Some have glass and the rest are covered with clear plexi-glass. Just across the hall and in sight from my office is a chrome-framed-glass-covered, Matt Groenig-autographed/dated "Simpsons" poster. Nice piece. And I believe it was under $75.00 to have it done...but then, this was back in '91. (Yep. It's that old...I think the poster was a "Welcome to FOX" gift when we became an affiliate.)
