I am ready to invest in both a mobile app and a companion website whose sole focus is to generate cash on day one. The product will sell my own goods and services directly, so every screen—from landing page to checkout—has to guide visitors toward a purchase. Here is what I need you to deliver: • A modern, responsive website and a native (or cross-platform) mobile app built from the same brand guidelines. • A clean product catalogue, seamless cart and checkout flow, and secure payment gateway integration. • Basic admin tools so I can upload new items, adjust prices, and track orders without touching code. • Clear hand-off: source code, deployment instructions, and working links in the relevant app stores or a ready-to-install package. Success to me means a smooth buying experience, no payment hiccups, and the first sale arriving quickly after launch. If you have a proven track record building revenue-first products, let’s talk about timelines and the best tech stack to get this online fast.
