I've created a template and a site at Zoho. It is the best I was able to do with what Zoho is offering. I'm not happy about the result but it is OK. Creating site on Zoho is difficult and very frustrating when some parts are disappearing for now obvious reason (even in Chrome).

Understand but it looks really good to me.

One question. Have you done this (or can you do this) as our custom template? This way we could quickly create other pages for different products and even our main website. And we can always work later on improving the theme.

I've done it as the theme, but it is not possible to reupload the same theme - it needs to be edited online. So making changes to the theme will be copying changes between our site project.

Yes, indeed. The theme is indeed there. Unfortunately it is not shared between different sites, which is annoying. I was able to download it from beagle.im site and upload it to Tigase site. This worked OK.

Links at the bottom to "About", "Features" and most importantly: "Contact" do not work.

I've fixed footer, but we still do not have anything to show on the "Contact" page. Do you have any idea what to put there? If you do, then, please fill this page (Contact page). I've tried but was not able to add "Features" section to the menu on the top as Zoho does not allow to link to the particular part of the page.

For now, I would direct users to our current contact page: https://tigase.tech/contact

Done.
