Tonneau cover with a rollbar

I want to get a tonneau cover for my S4 DHC but I have a roll bar fitted - usual thing like the photos in the recent thread - hoop, 2 rearward braces and a diagonal. I’ve seen other Elans with covers tailored around the tubes with extra fasteners and velcro. I asked an owner who had done this how it was done and he told me he had got an upholsterer to alter a standard cover, and it looked great. So far I haven’t found anyone willing to take it on unless I make a template first. I guess I’m just being a bit lazy here, but does anyone know 1) If anyone offers such a cover “off the shelf” or 2) can any one recommend some one who could do it? 3) Long shot here - does anyone have a spare they want to part with?

Thanks

Just a thought-instead of going around the rollbar-why not form a hood to go over it.Bit more work cutting/stiching but should be easier to fit and probably less chance of water penetration.
ps-paper template will give an idea of any cut required.
