Sun Blinds

Does anybody have a contact for a sun blind maker?Think of a conventional, rather old-fashioned roller blind with the roller fixed at the top of the window and the blind hanging vertically down. That is what I need, but the window in question is 3 metres wide and 2.5 metres deep, so it's a big blind. I want the roller to be a very simple manual thing and the blind material to be fairly sturdy, outdoor quality. I can't use a conventional outdoor blind with extending canopy etc as they only fit on the outside of buildings and I need mine to fit on the inside (it's a covered terrace with no access to the outside wall).I've searched all over the place but nobody seems to make stuff any longer, they all just import things ready-made from China. If anybody has a contact I would appreciate it, no matter where.cheers, Terry
