Promotional Post & Thumbnail Design

I want a concise, eye-catching promotional post aimed at the general public, paired with a matching thumbnail that instantly conveys the same message when it appears in feeds or preview cards. The post should feel upbeat and persuasive without sounding pushy, guiding viewers toward a clear call-to-action I will supply once we agree on the visual direction.

Here’s what I need from you:
• One ready-to-publish promotional graphic (1080×1080 px unless you recommend better) that looks great on Facebook, Instagram, LinkedIn, and X.
• One thumbnail or preview image that mirrors the post’s style but is optimized for smaller placements (ideally 1280×720 px).
• Layered working files (PSD, AI, or Canva) plus exported PNG/JPG versions.
• Font names and color codes so I can stay on-brand in future posts.

I’ll share my logo and any copy as soon as we start; feel free to suggest tweaks that boost clarity or engagement. Please keep the design fresh and readable on mobile, use royalty-free assets only, and let me review an initial concept before you refine the final artwork.
