Although, I suppose you can always go to a local machine shop and see if they'll work with you.

There's one problem I see with this service that is not addressed (at least anywhere that I could find): Tolerances
How does the software know what the part's tolerances need to be? For example, if your part has a hole that needs to slide over a shaft, how can you tighten up the standard tolerance so that the part's hole isn't overly sloppy? There's only one MCAD software package that allows you to dimension (as per ANSI or ASME standards) a sold model completely, while including geometric tolerancing and that program is Pro-E's Wildfire.
Of course, maybe they're expecting you to detail a 2D drawing after creating a 3D solid model, but most people with no drafting knowledge will have a hard time doing this adequately when mating parts are required.
Needless to say, I'm a bit skeptical!
