Refine Expo Banners

I have four AI-generated banner mock-ups for an upcoming industry expo and I now need them translated into polished, print-ready vector artwork. The existing colour scheme and overall layout already work, so those elements should remain intact; everything else is open for refinement so the designs feel professional, cohesive and on-brand.

Each vertical banner must clearly communicate one unifying line—“Solutions for dust, difficult waste and organic resource recovery”—to catch the eye of potential clients walking the exhibition floor. Think bold, legible typography, clean industrial imagery and a consistent visual language across the set.

Please rebuild the artwork in Adobe Illustrator (or another true vector tool) and deliver:

• Four CMYK banner files at the final pull-up size I’ll provide, with bleed and trim marks
• High-resolution print-ready PDFs
• The original unlocked .ai/.eps files for future edits

First draft within three days would be ideal, followed by a quick revision cycle so I can get everything to the printer on schedule.
