Commercial paper shears are an entirely different animal. These typically are large machines for commercial book binding. The have multi ton presses to shear volumes of posters, book pages, and catalogues. The will have no difficulty shear the binding off a book. They will leave a clean edge. They are quickly set up by clamping the book or stack of paper to the cutting bed, then a large razor sharp blade is brought down with tremendous force using a hydraulic pressure or a mechanical leverage system. I have used these to cut stacks of boxes at a previous employment.
I would not expect a print house, publishing firm , to charge more than a few dollars to do this, although scheduling might take a day or two. Maybe not just go in and do it on the spot, but leave for a day or two. Ask around at commercial print houses.

Paper shear works very nice for few cuts. FR4 laminate is glass epoxy
and that stuff make cutting blade dull very quick.
