Enterprise Podcast & Social Covers - $60 fixed price

I need a clean, institutional cover design system for an enterprise strategy brand.

Primary use: podcast cover art (Apple Podcasts / Spotify).
Secondary use: social and LinkedIn brand visuals (same design, no “podcast” wording).

This is not a consumer podcast or influencer brand. The visual direction should feel restrained, editorial, and comparable to top consulting firms (e.g., McKinsey, Accenture, Bain).

Requirements:
• Typography-first, minimalist design
• No microphones, faces, icons, emojis, or loud gradients
• Must work at very small sizes
• Corporate / institutional tone

Deliverables (IMPORTANT):
• Podcast cover: 3000 × 3000 px (Apple / Spotify spec)
• LinkedIn square version (no “podcast” wording)
• LinkedIn banner version
• General social square version (reusable)
• All files delivered in PowerPoint (so internal edits are possible)
• Exported PNGs for each size

I already have brand colors and typography direction.
Please share editorial or corporate brand work only in your proposal.
