Just as thought price up the rail you need and get a quote from a local engineering works to drill the holes for you? Factor in buying a box of drills (being that they are all the same size). You may be surprised that it could be cheaper than you think? I got a quote last year to have thirty holes drilled into some plate at odd angles (lots of machine set up time) for £30. They may look at the job as being just some holes drilled in a straight line?

Worth a punt?
