Custom Rockchip RV1126 PCB Design Modification (KiCad)

We are looking for an experienced hardware/PCB design engineer to create a customized board based on the Rockchip RV1126 processor, similar to the attached reference image.
Project Requirements:
• Must deliver the final source files natively in KiCad format.
• Preference will be given to freelancers who already have a proven, working, or open-source RV1126 schematic/layout baseline to speed up development.
• The task involves taking a base design and making specific hardware modifications (peripheral changes, connector modifications like J1-J5 interfaces, and form-factor adjustments).
Application Criteria:
In your proposal, please provide:
1. Proof of previous experience with high-speed PCB layouts or Rockchip processors (RV1126, RV1109, etc.).
2. A screenshot or confirmation that you possess an existing baseline design file you can adapt.
