I'm currently working on putting together my own RepRap, 500$ for a 3D printer? Awesome! Anyways, I have a laser that will cut up to 1" acrylic and a CNC mill as well. If you send your CAD file I can give you a quote on what the parts would cost. Visit my site
My CNC web site for more info, www.cncbydesign.com
In most cases I can be very competitive as my equipment isn't in the gazillion dollar range but it gets the job done.
Cheers,
Nathan Allen
