Binder Cashout: A webapp converts photos of a trade binder into priced, ready-to-post listings by matching each card against live market prices.

Start with a manual-matching MVP where you price uploaded binder photos for a flat fee, then automate card recognition.

Why it can work: Almost every collector owns a binder full of value they never list because pricing 100 cards feels overwhelming; automating that converts dead inventory into cash instantly.
