An office support place like Staples or Kinkos, or a local stationer, can make those for you in whatever format you want. Talk to a local shop to see what format they want you to provide, and about options.
Hubby needed some specific type of scorebooks that were commercially available 30+ years ago but not for a long time. He took an old one to a local place, asked "can you make me more of these?" and they could not only make them, they gave him the choice of glue-bound or spiral-bound, paper color, page count per book, quantity, etc - all for what he considered to be a VERY reasonable price.
