I will do sharepoint online UX branding design on modern experience

Yes, we'll create a root Communication site and have it swapped with your existing root site

We'll archive it for you once we swap it with the new modern communication site

We will recreate all the document libraries. Data migration (from documents and lists etc.) will have to be carried out by the client.

Refer to the Gig images. Or Contact Seller

Unfortunately, we don't build custom web parts. We use only Out-of-the-box web parts that's available on SharePoint Online. However, if the requirement could be achieved by making custom JSON formatting on a list, we could build it for you.

Team sites have the navigation on the left. However, we recommend a Hub site or a Communication site to be used as a root site. And Departments, or Cross-functional teams to be created as Team sites. (Eg. Accounts, Marketing, IT, HR etc.)

- Hero web part - Quick Links - Recent Documents (created or modified by the logged in user across all site collections) - Recent Sites (Frequently visited site collections) - News - Events Contact seller for further clarifications

Yes, tenant access is required to run PoweShell cmdlets in order to deploy the custom theme.

No, Sharepoint allows only one primary color, which would be used on Buttons, Links, Quick Links etc.

Unfortunately, as Microsoft is encouraging and moving towards the Modern Experience design, we advise all our clients to go with the Modern Site in order to avoid inconsistencies within the site.
