WordPress Multilingual & UX Upgrade

I want to add some new features to my WordPress website, such as the automatic translation plugin for multiple languages, to enhance the user experience of my website. I have compiled a document with the specific details of the work. Please refer to the document to understand the detailed tasks. Additionally, I also want to develop a new website. I would like to collaborate with a developer who can respond promptly and has excellent technical skills to upgrade my website. I am familiar with website development, so I would appreciate it if you could provide me with a reasonable estimate regarding the working hours.

Looking forward to your insights and a smooth collaboration.
