PDF Page Numbering Needed

I have a finished PDF that simply lacks page numbers. Your task is to insert clean, sequential numbers and return a print-ready PDF. Here’s what I already know I want: plain Arabic numerals (1, 2, 3 …) with no dashes or prefixes. I’m still open on the exact position and on whether we should skip a cover or intro page—feel free to suggest what looks most professional, or tell me if you can copy the standard positioning from similar documents. Key points you should follow • Work directly on the supplied PDF; do not down-sample or alter existing content. • Maintain full resolution and existing bookmarks/hyperlinks. • Deliver one final, flattened PDF with the new numbers applied. • Turnaround is urgent—please indicate the earliest you can hand it back. I’ll share the file as soon as we agree. If you use Acrobat Pro, InDesign, PDFtk, or any other reliable tool, just let me know so I’m confident the output will be flawless.
