>Having no technical people on some offices means that the initial installation would need an engineer the same way as a hardware replacement if the device fails.
Picking up on the "hardware replacement" - so this is for post-deployment.
With Cisco Support there are two categories of support; standard where they ship it to you and "onsite" where they send a person to swap it out ("they are like remote hands"). Onsite is not available everywhere in the world but does have extensive coverage.
So when you look at this document with the offerings, you would only be interested in the "onsite" options.
