Dual RTK heading system integration with px4 drone

I am looking for a freelancer who can help me integrate a dual RTK gps system with my px4 drone for heading angle correction. I am a beginner in RTK system integration, so I am seeking someone with expertise in this area.

Project Requirements:
- Integrate the dual RTK system with the px4 drone
- Achieve heading yaw correction form dual RTK.
- Already have achieved dual RTK setup for cm level positioning, so need to setup particularly heading angle.
- Currently using px4 firmware v1.13.0 and C-RTK 2HP gps device, I can upgrade pixhawk firmware version to v.1.14.0 if needed.
- Ensure seamless communication and synchronization between the RTK system and the drone
- Main task here is to find particular PX4 parameters to enable heading system.

Ideal Skills and Experience:
- Strong knowledge and experience in RTK system integration
- Proficiency in working with px4 drones and their software
- Familiarity with dual frequency RTK systems and their compatibility with drones
- Ability to troubleshoot and debug any integration issues that may arise

If you have the necessary skills and experience, please provide examples of previous projects and your proposed approach to this integration.
