Custom Exhibition Banner Design

I need a set of eye-catching banners for an upcoming exhibition. The focus is solely on banners (no posters or brochures) and they must be produced at custom dimensions measured in meters. I have not yet fixed the exact width and height, so I’d like your guidance on optimal sizing that will stand out in a typical booth space while remaining practical for production and transport.

Here’s what I’m looking for:
• Concept development based on my branding and event theme
• Two to three layout options presented for review
• Final artwork delivered as high-resolution, print-ready files (PDF and the editable source file—AI or PSD)
• CMYK color profile with 3 mm bleeds and clear safe zones
• A quick mock-up showing how the banner will look when installed

I’ll supply logos, copy, and brand colors once we start. Please include relevant portfolio pieces featuring large-format or exhibition graphics so I can see your style. I’m aiming for a clean, professional look that attracts visitors from across the hall.
