I use MS Word on a daily basis and can complete your task within the required timeframe. I've looked at your document - Technical Manual Operation, Maintenance, and Repair, 75 pages and dated from August 14 2018.
I will add headers and footers - anything specific required in the header/footer like company name, logo etc. I will create hyperlinks to figures, tables and contents page.
I should be able to complete the work within a few hours.
