Web-Based Exhibition PlatfVirtual Exhibition Websiteorm Creation

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.
