Book Cover Design Needed for Non-Fiction Finance Book "The Plumbing Tax" (Amazon KDP)

Description I'm looking for a talented book cover designer to create a striking, professional cover for my upcoming non-fiction book, "The Plumbing Tax." About the book: "The Plumbing Tax" explores how stablecoins are quietly rewriting the infrastructure the "plumbing" of the global financial system. Written in an accessible, narrative-driven style (think Malcolm Gladwell meets fintech), the book blends real human stories with big-picture economic analysis to explain why the money pipes we all rely on are being rebuilt, and what it means for the future of payments. What I'm looking for: A cover that feels premium, intelligent, and modern — the kind of design you'd expect from a top-tier business/finance bestseller (think authors like Michael Lewis, Malcolm Gladwell, or Matt Levine-style branding) Visual metaphor tied to the "plumbing"/infrastructure theme (pipes, flow, circuitry, financial rails, digital currency) but executed subtly and tastefully, not literally or cartoonish Typography-forward design that works as a small Amazon thumbnail as well as a full print wraparound A design that signals credibility and authority to a business/finance audience, while still standing out on a crowded Kindle store shelf Deliverables: Full book and e-book cover (Kindle-ready, KDP specs) Print cover with spine and back cover (6x9" trade paperback, KDP print specs I'll confirm final page count once trim is set) Source files (PSD/AI) so I can make minor text edits later 2-3 initial concepts before we lock in direction, followed by revisions on the chosen concept Ideal designer: Proven experience designing non-fiction/business book covers (please share portfolio examples, especially finance, tech, or economics titles) Strong typography skills. This cover will lean more on type and concept than illustration Familiar with Amazon KDP formatting requirements for both digital and print Can turn around initial concepts within about a week If you have designed covers for finance, tech, or "big idea" non-fiction books before, I'd love to see them. Please include 2-3 relevant portfolio links or samples with your proposal. Looking forward to seeing your take on this.
