I need a complete e-commerce solution for selling downloadable products—think software, templates, and PDFs. The project includes both a responsive website and companion mobile apps (iOS and Android), delivered as quickly as possible. Core requirements • Secure checkout for digital goods with instant, license-controlled downloads • User accounts with purchase history and re-download links • Clean admin dashboard where I can upload new files, set prices, and see sales stats • Push notifications on the apps for new releases and promotions • Modern UI/UX that looks consistent across web and mobile • SEO-ready pages and basic on-page optimization I’m platform-agnostic as long as updates are easy—WooCommerce, Shopify, Laravel, Flutter, React Native, or another proven stack are all fine. Source code, build files, and a brief hand-off guide are part of the final hand-over. Because I’ve marked this as ASAP, please outline your estimated timeline alongside any relevant live examples when you bid.
