My apologies if this has been asked before but I'm at my wits end. The author "my dad" has asked me to help make a revision for him since the previous helper is no longer available. I've been all over the website, internet and youtube for days and cannot figure out how to to this. The files on Lulu are all in pdf or jpeg. I followed the instructions on how to revise, but that's where I'm stuck. There are no files available / open to edit. Can someone please tell me how to do this. Lulu said they could do it for him but it would cost him over $900! He just needs to add 2 endorsements and complete the page numbering. No pages would be shifted or added. Thanks in advance for any suggestions.
