Multi-User Music Band Booking System

I need a straightforward, web-based booking manager dedicated to live music acts. The system must let three different user groups—admins, performers, and event organizers—log in and coordinate dates without stepping on each other’s toes. Core flow: organizers browse available bands, submit a booking request, performers confirm or counter, and admins keep ultimate control of approvals and edits.

A clean, shareable calendar that updates instantly for everyone is essential. Beyond that, I’m open to your recommended stack and UI approach as long as it delivers a smooth, clutter-free experience on desktop and mobile.

Deliverables
• Fully functional booking platform (front-end and back-end)
• Role-based access controls for the three user types
• Responsive calendar with real-time updates and basic conflict detection
• Source code with brief setup documentation

I value clear milestones and regular check-ins, so include a concise timeline with your proposal.
