Merge PDF files, add menu links (Python)

!!! Please read attached [login to view URL] file for details. Text here is an abstract due to character limit !!! Hello Python and PDF expoerts! I have a pdf file of product summary and several pdf files for individual products. I'd like you to develop a Python tool to make a PDF catalog by concatenating all PDF files, making links to product page from summary page, and adding navigation menu images onto all pages to link back to summary page. One of the technically challenging part of the project is No.3 below; search text in existing pdf and find its binding box so that link can be created. I already have a solution for it (based on PDFMiner) and I will provide the code so you can jump start. https://www.freelancer.com/projects/eBooks-English-US/Add-link-text-existing-pdf.html Required functionality ------------------------ 1. Read a csv file ([login to view URL] attached as example) which lists product part number and corresponding product pdf file name. 2. Concatenate the summary pdf file ([login to view URL] or [login to view URL]) and product pdf files in the order listed in [login to view URL], while keeping record of page count. 3. Search product part numbers in concatenated pdf and set link to the 1st page of corresponding product pdf 4. Read another csv file ([login to view URL]) which lists group name and corresponding group's summary page number. 5. Make navigation menu as an array of link buttons from [login to view URL] and overlaying group name text (refer [login to view URL] for layout). 6. Apply the menu to all pages (except page 1) UI: Simple command line interface is ok. For example > python [login to view URL] [login to view URL] [login to view URL] [login to view URL] [login to view URL] -p cutsaw (p option is password for [login to view URL] if encrypted) Special note: * Paper size and orientation is not constant. Overlaying link and navigation menu must be adjusted to each page size and orientation. * [login to view URL] may or may not be password protected. When protected, take extra argument for password to decrypt and encrypt back the result pdf. * The tool should preserve [login to view URL]'s security restriction meta data. (if you use PyPDF2 or pyPdf, this patch may help [login to view URL]) * Group names are "Top" and arbitrary number of one or two digit numbers. I'd expect max 15. Other requirements ------------------ * Use Python logging facility to output debug messages * Add reasonable amount of comments in code so that I can maintain it later * Try to follow PEP8 Style Guide for Python Code * Frequent communication; One line status update once in two days; describing which part you are working on * All the outcome of the project belong to the project owner What I provide as the project owner * Requirement (this document) * Example files (attached) * Reward as agreed at the start of project * Feedback as the project progress What you provide as a developer * Technical advice on requirements * Source code Project time frame and milestone ----------------------------------------------- I’d expect the project to be completed in about two weeks. 1st milestone: Requirements agreed and identified libraries to use (1/4 of reward) 2nd milestone: 1st version (proof of concept) submitted (1/4 of reward) 3rd milestone: 2nd version (functional) submitted (1/4 of reward) 4th milestone: Final version submitted and project completed (1/4 of reward)
