Modern Social Media Flyer Design

I’m launching a new service-based venture and need a set of eye-catching, modern, and sleek flyers that I can deploy across Facebook, Instagram, and WhatsApp simultaneously. The core message and branding will be the same on every platform; however, each file should be tailored to the ideal dimensions and technical requirements of the specific channel so the artwork looks crisp in a post, a story, or a status update.

Here’s what I’m after:
• One cohesive design concept applied in the three native sizes: 1080×1080 px (Instagram/Facebook feed), 1080×1920 px (stories), and 1080×1350 px (WhatsApp status).
• Editable source files (PSD or AI) plus exported high-resolution PNG/JPEG versions ready to publish.
• Clean typography, minimal color palette, and a subtle call-to-action that feels professional without losing approachability.

I’ll supply my preliminary brand colors, service description, and any imagery you might need as soon as we begin. Please show examples of similarly sleek social media creatives you’ve produced, highlight your typical turnaround time, and let me know how many minor revisions are included so we can keep the launch schedule tight.
