Corporate U survey

Okay, ladies, I would like your opinion. I have done some preliminary research of online CU consultant websites to get an idea of what their writing courses are like. Here's my criteria:
In order to get a glimpse of what is actually being taught in the corporate university classroom, I conducted an examination of seven corporate university consulting firms. The areas of focus for my study included:
 Types of writing classes
 Length/ Number of said courses
 Course content
 Method of delivery
 Type of Provider (non-academic consultant, university/academic courses)

The criteria used to choose which business writing consultant program would be included in the study included:
 The firms must serve at least one major corporation (consisting of 500 or more employees)

 The firm must serve a variety of industries (industrial, retail, etc.)

 The firm must have a website that contains information about the writing courses offered.

MY QUESTIONS TO YOU
1. I used this just to narrow my search, but maybe I should use other criteria?
2. How should I present these results? In other words, when I show this information during our presentations, what will make the most sense to you? I am not mathematician, and since I opted out of my statistics class for my Master's, I have no idea how to present this -- shorthand-- in a way that makes sense. HELP!! Here's just a bit of what I've gathered so far --I think I've found some interesting things-- I'll include them here, but be warned: It is RAW!

Online Research of Seven CU consulting Firms that design writing curriculum.
