Internet distribution and management

One of our branch offices is located in a business park with several other businesses, our company is the only company in the business park that is currently linked up to a direct fibre internet link (100 Mbps).
My directors would like to distribute this to the rest of the business park.
The idea is to create a private network within the park via fibre and UTP, basically fibre would be used as the backbone link between buildings and UTP inside the buildings to each business, managed switches would be installed in each building.
Each company would then be offered an option of required speed, basically what any ISP would do just on a much smaller scale

How would we be able to manage this so that each company remains isolated from the other and maintain a stable network, what type of switches would you recommend, what other hardware would we require?

Great idea but difficult to implement. In the short run it isn't cost effective and also creates more administrative work.

A managed switch with VLAN support is required. Personally I am familiar with Cisco and would buy used Cisco switches, such as the 2960 series. Each tenant would need to be on their own VLAN. You could then use a router or firewall to keep traffic separate and do bandwidth throttling. I agree that it could be a lot of trouble to implement.

I came up with a rough estimate on what it would cost to install one adjacent building and we worked it out to around 15k though the switches I was was looking at were the Cisco SG300-10PP, I would Imagine that a used switch would be cheaper.
The 15k would include a switch for one building, the fibre backbone to the building and a router, of course 15k isn't what each client would be charger.

Since you are offering services to others you should start about high availability, redundancy switches etc. You need at least one big reliable L3 switch (for redundancy 2 pieces) with optic ports, and at least one smaller L3 switch switch for each building and to be familiar with QoS (you will need it to limit and prioritize traffic for each client).

Sure, you can do it with different equipment, but challenges remain the same.

it's easier to use an router like ISR G2 2921. create for every customer an vlan and add an shaper to this vlan. you can then also use bursting. for a customer when the bandwitdh is available.

Sounds like a rather in depth and tasking exercise.
