Margin Adjustment for 310 Cards

I have 310 finished board-game card layouts that now need their margins brought in line with a precise print spec. The artwork and text are all final; the only change I require is shifting the safe, trim, and bleed areas so every card matches the measurements I will supply as soon as you come on board.

You will receive:
• The 310 source files (mostly layered PSD/AI, with a few PDF exports).
• A one-page guide listing the exact top, bottom, left, and right margins for each card size variant.

Your task:
• Open each file in Illustrator, Photoshop, or another vector‐friendly editor.
• Adjust the canvas and reposition elements so the new margins are met without distorting artwork.
• Export print-ready PDFs (300 dpi, CMYK, embedded fonts) plus the updated source files.

I will spot-check a small batch first; once those pass, we proceed with the remaining files. Let me know your preferred workflow and how quickly you can turn around the initial sample.
