And for anyone wanting to try drawing their own flanges, use a program called Draftsight http://www.3ds.com/products/draftsight/overview/
For people who know Autocad, it is 99.9% the same except legitimately free, made by Dassault (Solidworks company) because they got pissed off with Autodesk charging so much for Autocad
For people who dont know, it will take a bit of mucking around but it is a very capable program for making line drawings of things such as flanges. Anything drawn in this program can be sent to companies for laser cutting as a .dxf or .dwg format. You might be able to learn something and get a better price for laser cutting yourself
Also, as with many others here, I can draw things up if needed
From my experience, a 10mm steel flange cut to within 0.1mm costs around $50 when laser cutting with a usable drawing supplied
