Children's Book reprint preparation

I have a 27 page book that I am going to re-print but have lost the original artwork. I have scanned images from a photocopy of the pages but all the pages need cleaning up and some need minor changes such as a new logo and a change of text. Other than the covers, the pages are all grey scale and generally contain large images as the book is aimed at pre school age children. I've attached a typical page from the book. As you can see, images from the other side of the page are coming through and need to be cleaned off. Also the grey bar needs to be made much lighter and the hand symbols made much more visible. The spiral bind marks need removing and the image lengthened to an A4 ratio. Most pages need to be de-skewed also. A provisional task list for each page is also attached. After the images have been cleaned up, the images need to be placed into a print ready PDF.
