Custom 5M GTA V Server Development

I'm looking for an experienced developer to build a custom 5M server for GTA V. The server will require a variety of customizations, including:

- Custom Vehicles: You'll need to design and implement unique vehicles that fit within the game's universe.
- Custom Scripts: This will involve creating new gameplay mechanics, features, and enhancements.
- Custom Crypto In-Game Payment System: I need a fully integrated cryptocurrency payment system. This system will be used for all in-game transactions.

The most critical aspect of the server's functionality will be the seamless integration of the in-game payment system. Your expertise in this area will be key to the project's success.

Skills & Experience Required:
- Proficiency in server development for GTA V, particularly with the 5M platform.
- Strong coding skills for creating custom scripts.
- Experience in designing and implementing custom vehicles.
- Familiarity with integrating cryptocurrency systems into games.
- Good understanding of gameplay mechanics and ability to enhance them.

Your ability to deliver a smooth, engaging, and fun gameplay experience will be vital. Looking forward to your proposals.
