You can ask at a local copy/print shop, they often have the material and tools to turn a stack of paper into a binder or other book-like thing. They probably also have a good deal on printing a large number of pages :)
If you ask, some will even accept PDFs to print for you, so you can come back at a later time to pick up the finished binder/booklets.
Not sure if that's strictly legal, but many copy shops won't care and frankly, since you got the PDFs legally I don't really see the problem--in a pragmatic sense that is, going by copyright law, maybe. In some places you do have the right to transfer (copy) copyrighted stuff you have a license for (which is the case here) to another medium. But then you're not allowed to sell or give away that copy (not that anyone will check this ever, but it does make sense to have that as a rule).
