Oh, and you'd be better off to waterjet it than laser cut it. Laser cutting is better for steel, waterjet is best for aluminum. Aluminum dissipates the heat of a later too quickly, and steel is tough to water jet. Either will work on either metal, waterjet is more efficient on .060 aluminum. Cost will be higher if you don't hand them a CAD file and they have to program it. Maybe Joe's guy is the one to talk to if he's still under $100...
