Combining information from 8 columns

Hello,
I have a spreadsheet with 8 columns of data including the following headings

Business Name, Street #, Street Name,Tel #, Contact Name, Contact #, Alternate Contact, Alt. #

I would like to be able to sort the information by both alphabetical business name and also the street # and name. I cannot figure out how to link all the information so that when I sort the info it doesn't just sort the one column it sorts all the information with it.

thanks for your help.
