Pdf pages to crop & adjust + write index / table of contents

Here are 15 – 20 pdf files – scanned from a recipe folder/
Each pdf file has between 1 and 28 pages. Almost all are A5 in size. They are going to be printed on A4 sheets. There is no need to change the scale or positioning of the a5 scan on the a4 sheet).
The tasks are simply to;
a) Remove any blank sheets from each file (blank sheets are those on which there is “no writing” (there may be ruler lines and stains).
b) Double check that each a5 image will print on a separate a4 sheet. My impression is that they are all separated onto individual pages but just double check.
c) Straighten edges of the scanned pages where they are scanned slightly askew (eg adobe enhance tool)
d) Create a quick index table of contents. This needs to be no more than

Col 1: Name of dish - Col 2: Section - Col 3: page number within the section

Eg

Christmas pudding: Hot puddings: 1:
Keep this as a word doc not a pdf for subsequent adjustment.

e) Reassemble twice. Once and the individual pdfs as they are in the folder and again as a single full length pdf ready for priting.

Therre is no need to tidy the scans – remove holes tear marks folds or blotches – as they are is part of their charm

I estimate this to be no more than 45 mins work.

Please make sure you have seen the documents and are happy before tendering. They are here: https://drive.google.com/drive/folders/1bn2bPIMWGzksLIW9IdthNh6vyGhPs4U3?usp=sharing
