Custom xml for Opencart3

I am looking for a freelancer who can help me create a custom XML structure for my Opencart3 website.

Specific requirements:
- Creating a custom XML structure for my website
- I can provide a sample or a sketch for the layout and design of the new XML structure

Experience and skills required:
- Strong knowledge of Opencart3 and XML
- Ability to create custom XML structures
- Experience with designing XML layouts
- Familiarity with Opencart3 extensions and plugins

Please note:
- I have already installed a few extensions and plugins that may affect the XML structure, so the freelancer should be able to work around them.
