Modern Poster Design Needed ASAP -- 2

I need a sleek, modern poster created from scratch. The message and basic content are ready on my side; what’s missing is the visual punch—clean typography, contemporary colour choices, and balanced layout that will look just as sharp on screen as it does in print.

The finished artwork must be:
• Print-ready at 300 dpi, CMYK
• Sized for an A3 sheet (with bleed)
• Supplied as a layered PSD or AI file, plus a web-optimised JPEG/PNG

Turnaround within three days would be perfect. If you’ve produced modern-style posters before, please include a couple of examples when you get in touch so I can quickly see if our aesthetics align.
