Script to rename documents from text within the document itself?

The original file is a series of letters to send to customers.  Each letter is two pages long; I already have an action to break the document up by two's and add a letterhead logo before saving each as a new file.  I used javascript to separate them because I wasn't familiar with Acrobat's capabilities at the time.  The customer's name is listed on each letter in the exact same place on each document.  Is there any script that would be able to "read" the customer name (given it's in the same location on the first page of each letter) and save the file as that name?  I thought I was smart when I found out a script to separate the file, so I'm not a high-level thinker when it comes to this.  Any places to point me if there isn't a straight solution?
