Bold 300x250 Banner Resizing

I already have a handful of display ads for my online tele-medicine service that offers GLP-1 weight-loss medication. They look good, but the dimensions and file sizes aren’t ad-network compliant. I need five new banners produced at 300 × 250 px, each under 300 KB, keeping the same energetic, bold, attention-grabbing style.

The key copy on every banner should focus on our promotional offer; feel free to refine the phrasing for maximum impact as long as the offer remains clear. You may use the existing artwork as a starting point or rebuild from scratch—whichever achieves the cleanest result. I can supply logos, brand colours, and fonts on request, but they’re optional if a simpler layout lands better within the size limit.

Deliverables:
• 5 static or lightweight animated banners, 300 × 250 px, ≤ 300 KB each
• Final files in both layered source format (PSD/AI) and ready-to-upload web format (PNG/JPG/GIF)
• Quick preview proofs so we can lock the copy and visual hierarchy before final export

I’m looking for crisp alignment, sharp text, and colour choices that pop on any background. Let me know your turnaround time and any questions you have about the existing assets—I’m ready to move quickly.
