InDesign GREP code help

Hello all,

In InDesign CS6 I'm dealing with a bunch of listings for a directory. Each listing requires multiple styles and I'm wondering what GREP code might be used, if possible, to get the job done.

An example listing reads as follows:

     NAME OF COMPANY                 

     Company address

     Company contact info

     Company phone number

     Booth(s): 2129

     Description of company.

This is how the final should appear:

I've already created the desired character styles.

I need to format the name of the company, which sometimes continues onto the second line,

and I need to format each line that starts with "Booth(s):...", which is followed by a sequence of numbers.

The rest can be styled as body copy.

Any advice on how to get this done? Thanks a lot!!
