iansinclair: true... I'm meeting with the other pianist today (in a few hours, since it's 05:55 right now in Greece and I just woke up!

) and I'll discus with her the various options and people we can use.
Bob: It will be a normally sized and bound published score. Think of a Henle score, for example...

enrique: Thanks. Problem is that neither of us has a tablet, ipad (personally don't fancy anything with an "i" in front, but that's just me

). Plus I get a feeling that for a score for 4 hands, where one needs to view BOTH pages at the same time, any tablet or even single computer screen will be insufficient.
I was, however, talking with a couple of reviewers, who wanted to give it a try, so why not!?
Thank you all. You've been very helpful!
