PDF Merge, Split & English Re-write

I have a batch of PDFs that need precise structural changes and a language upgrade. First, several separate PDFs must be brought together into one cohesive file, while one larger PDF has to be broken down into smaller, logically named parts. I will supply clear page ranges and the exact order in which everything should appear, so you can merge, split, and, where required, reorder pages without losing quality or bookmarks.

Alongside the page work, the text inside each final file should read in polished, professional English. Please translate any non-English passages you encounter and add a short, clear description at the start of every new section so the contents are easy to scan.

Deliverables
• One master PDF created from the files I indicate
• Individual split PDFs from the source document, each correctly titled
• All documents in flawless English with concise introductions

Accuracy is crucial—no missing pages, broken links, or formatting glitches. Adobe Acrobat, Foxit PhantomPDF, or any comparable tool is fine as long as the final PDFs are print-ready and the translations meet a professional standard.
