Need a reliable upholstery cleaner - home visits

Hi everyone,

I am now looking for a reliable upholstery cleaner who comes recommended by a customer.  I have a 2nd hand sofa which is the only one ever made by a designer, which is very special and also very grubby.  I wonder if anyone uses home-visit fabric cleaners anymore? I've never had it done before, so i have no idea. The fabric is very delicate so i would need someone good and with tiptop cleaning technology.

Thanks for any help people!!
