This book is pretty brilliant. We actually scanned pics of the Choquequirao trek pages with our phones (Tinyscan app), then saved them as a pdf on our kindles. Portable guidebook!
Hopefully it's alright with /u/mysoju1 - I'll PM you a Google doc of our conversation back and forth, as I asked questions while planning this out 8 months ago.
If anyone else happens to be reading this - especially if you googled the trek, like I did - feel free to PM me for the same info!
