PDF Text Updates Required

I have a customer-facing PDF that needs a quick but precise text overhaul. The main file is already designed; however, several passages describing our product and service offerings have changed since the document was last published.

Here is what I need from you:
• Replace outdated product/service details with the new copy I will supply.
- Re-arrange product placement and categorize
• Keep every font, style, and placement intact so the finished file is visually identical to the original—only the wording should differ.

Please return the edited PDF ready for immediate distribution, plus an editable source version (InDesign, Illustrator, or Acrobat-friendly) so we can tweak minor items in the future. Accuracy is critical; I will cross-check all text against the new content. If you have experience editing locked or flattened PDFs, let me know—speed and a clean, artifact-free result are what I’m after.
