Printing spiral-bound campaign books

Okay, I've looked all over this sub and can't seem to find the answer to this ...

I want to print the complete campaign guides for older campaigns (Dunwich, Carcosa etc) in a spiral-bound style to match the new campaign expansions, because I'm an older player and my Dunwich etc rules are all scattered amongst individual mythos pack sheets.

I've found guides to print choose-your-own-adventure style 200-page hardback books. I've found guides to print small square books. I've found guides incorporating all the Return To content. I don't want any of those. I just want the campaign expansion guide, from FFG's site, printed in the size it is, as it comes, in spiral binding, to match the newer guides.

Is this possible? Cos it feels like it should be. It feels like it should be much easier than all the bespoke solutions I'm finding. But I can't figure out how or where to do it. Ideally I want a site that I can upload that guide to, click 'spiral' and put my payment details in.

Please help me 😫
