Social Media Banner Design Needed

I’m looking for a creative graphic designer to craft eye-catching social media banners tailored specifically for Facebook and Instagram. I will supply my brand’s logo, color palette, copy, and any imagery once we kick off. What I need from you is a cohesive set of banners that look great in each platform’s native dimensions, stay faithful to my visual identity, and stop users mid-scroll. Please include: • One Facebook-optimised banner (current recommended 1200 × 628 px or similar) • One Instagram-optimised banner (square 1080 × 1080 px) • Editable source files (PSD or AI) plus high-resolution PNG/JPG exports A quick turnaround and openness to a round of minor tweaks will be appreciated. If you have relevant portfolio pieces, share a link so I can gauge your style before we get started.
