Cost of fiber run between neighbouring office buildings

[Hank Disuko <gourmetcisco () hotmail com>]

Hi folks, 

I wonder if I can tap into some knowledge on the list and ask for ballpark figures on how much it would normally cost 
to run 2 fiber cables between 2 adjacent office buildings.  I have a quote from a contractor, and I want to make sure 
i'm not getting totally fleeced.

The conduit is in place between the buildings.

The work entails:

 - 2 x 6-Strand 50/125u multimode, Tight Buffered, Armoured, Laser Ultra-Fox Fiber cables
 - Distance of run is approx 520 meters
 - Total of 8 terminations (2 strands on each end of links)
 - Testing, documentation

Thanks,
Hank
