Content-Rich Educational Website Development

I’m building an online learning hub that offers a mix of free and paid PDF resources alongside supporting content—text articles, video tutorials, and interactive quizzes. Every visitor should be able to browse the catalogue, but anyone who wants to download, save progress, or purchase material must first create an account and sign in. For the PDFs, I need a clean structure that lets me tag each file by subject and clearly separate what’s free from what’s premium. From the user side, that means intuitive browsing, filters for subjects, and an obvious badge that shows whether a document is complimentary or requires payment. From the admin side, I want a straightforward dashboard where I can upload files, set prices, and switch a resource between free and paid with one click. Paid items will require a secure checkout—Stripe or PayPal is fine as long as transactions are logged and receipts are emailed automatically. Once a purchase is complete, the file should unlock instantly in the user’s library for future re-downloads. Core expectations: • Modern, mobile-responsive UI/UX • Secure registration/login with password reset (social logins optional but welcome) • CMS tools to publish/edit articles, videos, quizzes, and PDFs • Search and filter by subject plus free/paid toggle • Payment gateway integration and order history per user • Clear documentation so I can maintain content without touching code When handing over the project, please deploy it to a live host, share all source files, and walk me through the admin panel. I’m open to your recommended tech stack—just focus on stability, scalability, and ease of content management.
