Shutter Repair At Cagneys

Does anyone out there know of someone who could come to Cagneys and replace a shutter cord that a guest has kindly snapped without telling me?
I had one replaced in another bedroom 2 years ago. It's a very quick job and the materials are cheap, ie. a piece of new cord.
I need it replaced by this Wednesday coming for guests to be able to use the room.
Thanks
