Ah, so, to cost your proposal:
New hardware, $750. (Nothing spare, sorry.)
OS Installation and configuration, say 4 hours, for $572.
Ongoing maintenance and running costs, say $500 per annum.
That doesn't sound all that much better than the first option, to me,
though it does scale more slowly to the number of users. :)

Sure. I make no claim that it is impossible, simply that it is hard and
costly. You don't happen to know what their internal cost for that
project was, do you?
(I would bet at least a couple of full time people for a couple of
weeks, plus planning and management overheads.)
Again, as I wrote:
