Facebook Promotional Poster Design

I need a visually striking Facebook poster that highlights a limited-time offer and speaks directly to an adult audience. The piece should immediately capture attention in the feed, communicate urgency without feeling pushy, and stay on-brand with clean, modern aesthetics.

Deliverable:
• One ready-to-upload Facebook image (1200×1500 px or the platform’s latest recommended size) in both editable source file and high-resolution JPG/PNG.

Please use typography and color contrasts that enhance readability on mobile, integrate my logo and the offer copy I’ll supply, and leave safe margins so nothing gets cropped in previews. Let me know how many initial concepts you can show and your typical turnaround for revisions.
