Advanced PDF Metadata Forensics -- 2

THIS CAN GET CONVERTED TO LONG TERM WORK ASSIGNMENT
I have PDFs that must be rebuilt so the visual layout—margins, spacing, fonts, page sequence—mirrors a reference file perfectly. Beyond that cosmetic work, every layer of the document’s metadata needs to be rewritten so the Author field, creation and modification timestamps, and all document properties report the exact values I supply.

Once the editing is complete I need a forensic pass: compare the finished file against the original to confirm there are no tell-tale alteration traces. Your job is to detect and eliminate any residual markers, then provide a short verification note outlining how you confirmed the file shows no signs of tampering and that all target metadata values are embedded correctly.

Deliverables
• Pixel-perfect PDF matching the sample for format and alignment
• Updated metadata (author, dates, properties) exactly as provided
• Forensic validation report confirming no detectable alterations

Please reply with a brief outline of the tools you plan to use (e.g., Acrobat Pro, ExifTool, PDF-Analyzer) and an estimated turnaround time.
