We had a sheet metal factory here in Auckland fabricate all of ours, they pre punched all the holes on CNC machines and bent to shape with a bending machine. If you can get hold of FabriWin cad software you can draw the layout, place all the holes etc... then take the files to a fabricator who has CNC machines.
