Modern Minimalist Book Cover Design

I’m releasing a new book and need a sharp, modern-minimalist cover turned around quickly. The brief is straightforward:

• Create a sleek front cover that relies on clean typography and strong negative space—no ornate flourishes or busy imagery.
• Deliver a print-ready PDF plus a high-resolution PNG/JPG for online promos.
• Include the editable source file (AI, PSD, or InDesign) so I can tweak subtitle wording later if needed.

I haven’t locked down a color palette, so feel free to suggest a single bold accent or stick to classic black-and-white—whichever best supports the minimalist feel. If you can also mock up a simple spine and back layout within the same timeframe, great, but the front cover is the priority.

Experience with book branding and quick turnarounds is essential, and familiarity with Amazon KDP specs or similar platforms will be a bonus. Please mention relevant portfolio pieces and let me know how soon you can deliver the first concept; I’m aiming to approve a final cover within a couple of days.
