WordPress website and 3D Configuration Improvements

I am looking for a professional WordPress and eCommerce developer to improve my friend's website, https://besparta.com/product/sparta-3d-experience. The focus of this project is on enhancing the 3D configuration feature and overall website functionality.

For the 3D configuration, I need:
- Enhanced visual quality of the 3D models.
- Additional customization options for users.
- Optimized performance to improve loading speed.

Beyond the 3D feature, the website also requires:
- Improved user interface design for a better overall user experience.
- Enhanced mobile responsiveness to ensure seamless functionality on all devices.

The existing 3D models will be retained, so updates will focus on improving the 3D viewing experience and usability. You can reference the configuration on https://tailortech.revitsport.com/en/leather-motorcycle-suit-x_301/ for inspiration or approaches.

If you're experienced in optimizing WordPress websites, integrating advanced eCommerce solutions, and handling 3D customization tools, I'd love to hear your ideas and suggestions for this project.
