I am installing a new network between 3 sites the first building being the main site the second building is just over the road and the 3rd site is 1.8Km away.

It's difficult to advise you on what kind of switch to get, not knowing your infrastructure, what kind of traffic goes over the network, number of users, uptime requirement, etc...
If you don't need any kind of chassis redundancy, and you just need to connect the buildings together, you can probably use the 3500 switches, otherwise I would go with Cat 6000/6500. All these switches use GBICs and you have the choice between the SX (short-haul), LX/LH (Long Haul...that's the one you need to reach 1.8km) and ZX (extended distances).
