Reupholstering sofa

Dear all, I want to get my sofa reupholstered - the cats have really done a number on it. Do you have any recommendations of companies/shops that do this sort of thing? It's a three-seater fabric sofa. The cushion covers are removable but not the fabric on the chassis of the sofa, if that makes sense, so the sofa must go to the reupholsterer.

Many thanks.
