Convert MS Word documents to Adobe Robohelp

We have a collection of technical documentation in .docx format (10+ documents, several hundred pages each). They need to be converted into Adobe RoboHelp (v2019) project format. After conversion it is required to check if all the formatting / alignment / etc. is correct and fix the places where something is off

Requirements
The RoboHelp project has the same title as the source Microsoft Word document.
All chapters from the initial document are transferred into the RoboHelp project format.
All of the original formatting is preserved: fonts, headings, formatting (bold, italics, code blocks, etc.)

To do this, see the original document + use the CSS file with predefined styles & formatting as supplied (attached CSS file for Adobe RoboHelp) when importing the Microsoft Word document.

Checklist
All indentation in the resulting project is correct (especially important for lists and images).
A correct table of contents is present (the same TOC as in the Word document, with the same heading levels preserved).
All the links within the document work (links from one chapter to another).
All the links to external resources and email addresses work.
All 'Notes' in the source document retain their formatting (red color, original font, ‘NOTE’ is capitalized+bold, but the colon after ‘NOTE’ is not bold).
Special characters are displayed correctly (®, ©, etc.).
Make sure that PortaSIP®, PortaBilling®, PortaSwitch® preserve the ® when used in the body of the text. No ® in headings.
No invisible non-printable characters present in headings/chapter titles (so as to prevent “chapter.htm” from turning into “↲chapter.htm” after exporting the RoboHelp HTML5 output of the project if an extra invisible non-printable character was present in the original Microsoft Word file).
Make sure there is an empty line between an image and the text.
Make sure there are no extra empty lines between the tables and the text.
All the content in the Contents tab is sorted into folders and all folders follow the TOC and structure of the original Microsoft Word document.

Lists
All the lists are displayed correctly, no extra lines between the items on the list.
All the numbered lists preserve the original numbering.
Nesting lists remain nesting lists (with correct indentation levels).

Tables
Tables have the same size ratio as in the source document and look clean overall.
Make sure to verify that the title row has a grey shading (the grey shading is set in the supplied CSS).

Images
All images, screenshots, illustrations, photos, etc. must be exported (no missing image files).
All images, screenshots, illustrations, photos, etc. must preserve the original quality level as in the source document (clear, non-overcompressed, non-blurry).
All images, screenshots, illustrations, photos, etc. must preserve the original Alternative text (if present).
For images, screenshots, illustrations, photos, etc. that have no meaningful Alternative text in the original Microsoft Word document, add a placeholder Alternative text that follows the pattern ChapterTitle-SubChapter-Image-0X
(e.g., Intro-AboutPortaSwitch-Image-01).
All images retain the same scaling size as present in the source document
All images imported with “Use Thumbnail” setting on (checkbox):
Specify the image width:
Screenshot width - 1000 (4 panels), 750 (3 panels), 500 (2 panels), 250 (1 panel)
Illustration width -  750, 500, 350 or 250 (depends on the visibility)
Check the Use Thumbnail box and duplicate the image width from the previous step.

I can provide an example file that needs to be converted upon request
