Have a need to install a fabric in two new buildings located approximately 1/4 to 1/2 mile apart and connect them. Needs to be a cheap solution for the budget that I have. Does this distance eliminate ISL connectivity? Should I use a extended fabric license on an appropriate level switdh or would I have to go to a 7800 switch?

You can use which ever switch meets your port requirments/budget, What you need is the correct SFPs to push your fabric over the distance. The extend fabric license is really only used for very long distances.

David is right and I would like to add that it is important to know which bandwidth / IO demand (which kind of traffic) you have between both buildings.
A second important thing is: Did you have sufficient private dark fiber connections between both buildings then you can use Brocade longwave SFPs (cheap) if not you need a CWDM solution with colored SFPs (expensive).
The last point to keep in mind is security if you transport data over public lines.
All my points are directly related to costs....
I hope this helps,
