Comprehensive 1win Betting Script with Live Broadcast

I'm looking for a seasoned developer to create a complete betting script similar to 1win. The script should accommodate various betting formats, inclusive of:

- Live Betting: Users should be able to place bets on ongoing events.
- Pre-match Betting: This should cater to users who want to bet on events before they start.
- Virtual Sports Betting: Incorporate a section for betting on virtual sports.

In addition to the core betting functionalities, I want the script to have:

- User Authentication: A secure system for user registration and login.
- Payment Gateway Integration: Seamless and secure transactions.
- Real-time Notifications: Inform users of important updates and changes in real time.

A crucial part of this project is the incorporation of live video streaming for the broadcasting of live events. The script should be able to support this feature effectively.

Ideal candidates for this project should have:
- Extensive experience with developing betting scripts or similar applications.
- Strong skills in integrating payment gateways and user authentication systems.
- Proficiency in implementing real-time notification systems and live video streaming capabilities.

I look forward to receiving your bids and discussing this project further.
