Resize 28-Page Brochure

I have an existing 28-page brochure laid out in Adobe Illustrator at A5 size. I need it resized to A4 right away so I can send it straight to the printer. Print quality is my top priority, so please set up a proper 3 mm bleed all around, extend any background elements into that bleed, and keep trim marks clean. I only want the layout enlarged—no redesigning of text or imagery—just a precise, proportional resize that preserves everything exactly as is.

When you finish, I’ll need a press-ready PDF (CMYK, 300 dpi, bleed and crop marks included) plus the updated .ai file. A quick turnaround today would be ideal.
