Professional School Bus Sticker Design

I need a fresh, professional-looking sticker designed for our fleet of school buses and prepared for print. The final artwork should be press-ready (CMYK, 300 dpi, with a 3 mm bleed) so I can send it straight to the printer without extra tweaks. Feel free to propose a size that balances visibility and cost; I’ll confirm exact dimensions once I see a draft.

Please deliver:
• One print-ready PDF and the editable source file (AI or PSD).
• A quick mock-up on a yellow bus photo so I can visualise placement.

Clean typography, clear legibility from a distance, and an overall professional aesthetic are key acceptance criteria.
