[GLLUG] Emergency Internet connection may be needed tomorrow?

[Adam McDougall]

I have a building of approx 20 people with a broken high speed 
internet connection (panel antenna flew off from 65 ft up a tower).
It is scheduled to be worked on and hopefully fixed in the morning
tomorrow, but what are my local options to arrange for a temporary
internet connection with considerably higher speed than dialup modem? 
It would have to be established by approx noon tomorrow.

The alternative is to have a second tower monkey with a spare ~13db
panel antenna either fix it today, or tomorrow afternoon, but I am
interested in emergency complete solutions regardless.
