Dear Arthon,

I am not entirely sure about the layout of your network but it sounds like it's a mesh rather than a star or a hierarchical star as it supposed to be in Ethernet. In order to use any Ethernet equipment for that you would need to find ways to break multiple connections from a point and make sure that there is only one way from any particular point in your network back to the central switch.
As far as the lengths are concerned, most of your "Hub to X" links are beyond the standard capability of Ethernet-over-twisted pair being it 10BASE-T, 100 or 1000BASE-T for that matter. You are going to need to plan on using fiber optics to connect devices over that distance.

So, as you correctly pointed out, this is a rather big deal of a networking project and I sincerely recommend that you find a local expert that can survey the site, sit down with you and go over all the little details that make a more concrete answer over the Internet impossible.

Dmitri Abaimov, RCDD
