Can you find the parts you need online, then fix them yourself?
While on this matter, a few years ago I was visiting a friend and commented on her pretty vertical blinds. She told me to take a closer look. Haha, marvellous ingenuity! She couldn't afford the ones she wanted for her whole house, so had bought the tracks and fittings, then cut up strips of wallpaper, glued them together and they were the blinds!!
That way you can co-ordinate to different rooms, have both sides the same or mix & match etc.
And be totally different from your neighbours, too!
