You can run upto 1.5 miles on a lx fiber based solution but will likely 
require a skilled installer to setup that much cable for you.

Depending on your locale I am may be able to put connect you to a supplier.

Have you considered a wireless direct beam solution?  Especially 
considering the 'temporary' nature of this install.
