I would like to develop a web-based exhibition website with the ability to add more features in future phases. The first stage will be a limited testing phase to ensure the system works properly before expansion. A temporary access account will be provided to the developer, and access will be removed after project completion. Required Features: User Pages (for each added user) Each user should have a dedicated page where they can: - Upload images - Upload videos - Add products - Edit their basic information During the testing phase, the system must support no fewer than 20 users, with the ability to increase this number later if needed. Administration & Review: - Simple admin dashboard - Ability to review and approve user content - Ability to manage categories and sections Additional Features: - Integration of live streaming via YouTube Live (or similar) - Clean and easy-to-use interface - The system must be flexible and scalable for future updates Developer Requirements: - Recommend the best technical stack (Laravel, Node.js, React, Next.js, etc.) - Provide estimated development time - Provide cost estimation - Share similar previous work if available Project Goal: To launch a test-ready website for a 3‑day virtual exhibition, with the ability to expand the system in future phases.
