I came across this the other day, and thought some of you might find it useful: http://sendcutsend.com (http://sendcutsend.com)
I uploaded an Adobe Illustrator files to their website, and within a week had my finished parts in hand. At $48 (including shipping) for an 8.5 x 11" layout in 14ga Aluminum, they are very reasonable. They do have a limited selection of thicknesses, and don't like parts smaller than 1/16" - I guess this is how they keep cost down.
Here are some photos of what I had cut:
