Web Content from 1 site to another

Description

I have an established wordpress website that uses an old wordpress theme. We have created a new website, with a new theme, created page templates etc. We now need someone to spend the time taking the content from the old website and applying it to the new website.
To note, this is not a copy and paste job. This is carefully choosing new titles, copying the current words and applying them to the new website, ensuring the new pages fit with the new style. You'll also need to ensure that the content is SEO evaluated.
We have 48 pages that require transferring. We have already completed a couple ourselves and find it takes us around 2 hours to do each page properly.
Current site example page: https://www.imsm.com/gb/iso-9001/
How the page looks on the new site: https://staging.imsm.dev/iso-9001/
To note, the website pages are all in place. We just need you to select various pre-defined modules and apply the text and imagery.
