That really depends how you want it done. The range of binding goes from comb-binding that you can have done in Kall Kwik or Prontaprint (�5-10) to specialist leather binding at the other extreme (�100s). Do you want the letters produced in facsimile (in which case they'll have to be scanned) or just bound as they are (perhaps mounted on paper or card)? Any printer or binder (see yellow pages for local firms) will talk you through what you can have done. You may also want to have the book designed and laid out, in which case you'll want a designer - unless you're up to doing it yourself. If you wnat to be more specific as to your requirements, one of the answerbank users might be able to give you more concrete advice.
