Computer help needed due to lightening strike

At work, we have 5 85ft. long bays for working on our trucks. At each side of the doors there are 6 inch steel poles to protect the building.

7 years ago, during 1 of the famous Florida storms, one of the poles took a direct hit. Looked like 20 plasma cutters went to work on it.
Took out our phone and electrical systems as well as our computers.
We were running the company on cell phones and laptops out of an RV for almost 2 weeks.
