You can probably find a number of companies around you that can do this kind of cutting in any kind of metal but it may take some digging - they aren't necessarily in the yellow pages. Start by looking for machine shops and ask for references to shops with steel cutting lasers or water jet cutters - we have two or three other companies in town with this capability. I'll be glad to send you my DXF file to give them. .06 aluminum would probably be the best and most economical choice for making these.
