Hi Krishna As George has said there are some variables to be considered. Size and condition of walls to be papered, matching or non matching paper, standard width or wide vinyl, paste requirments for chosen paper, Access requirements, does the work need to be done out of hours with it being your resteraunt. All those factors will affect the price given by a decorator. Once these factors are known, usually by a site visit the chosen decorator can then price either per roll, or per m2. Hope this is of some help Paul
