Exact PDF Text Re-Typing

I have a PDF made up of text only and I need every word reproduced with complete accuracy in a plain .txt file. Please keep the flow of the original paragraphs, but there is no need to mimic fonts, margins, headers, or any other styling—simple, clean paragraphs are enough. Spelling, punctuation, and line order must match the source exactly, so careful proofreading before delivery is essential. Deliverable • A single UTF-8 plain-text file (.txt) containing the full content of the PDF, laid out in straightforward paragraphs with one blank line separating each paragraph. I will provide the PDF as soon as we start; you return the finished text file when done. Let me know your expected turnaround time and any questions you have about the layout requirements.
