Hi there,
I have read your project requirements and understand what is it that you are looking for, which is to make edits to a pdf file. If that is the case I will suggest that InDesign is a better application to use for editing documents such as that, which can also save print ready formats, should you wish to print this document.
I have knowledge and skills with this application, as well as Photoshop, but more importantly experience in editing documents.
Please contact me via chat, so we can discuss the details for the project further and agree on the time frame.
Look forward to hearing from you soon.
Kind regards,
Nikolay
