A PDC Pamphlet/Infographic design

So as a hypothetical, let's say you wanted to make a 1 to 2 page pamphlet/infographic on what a PDC is and how they work. Further assume that we're trying to keep the sentences short and favor visual representation of information wherever possible. What sort of information would you include and what type of answers would you propose to offer? For my own part, I so far have the following list of things to cover:

Where does the idea originate?
What is the basic concept of how they work?
How to find one that will meet your needs and expectations?
What are the different schools of thought associated with them?
What can you expect and what topics will be covered?
What is a typical cost?
What is kind of time commitments are there?
How can you tell what value you will get?

Some of these, such as the first, are easy to answer with brevity. Others like typical costs or topics covered might be a bit trickier to answer without getting long-winded.

I think for something as costly as a PDC, some paragraphs of info may be worthwhile in a few cases.

Additional possible topics:
What do you gain with a PDC that you don't gain by reading and the internet?
Does completing a PDC give you a certification?
What does that certification do for you?
How can you assess the quality of the PDC before purchasing?

Mike brought up some good points. For myself, I'd also be very interested in more details on:
- schools of thought about permaculture, especially which one this course follows
- topics covered in the course
- typical cost and what that includes (housing? meals?)

The first permaculture book I read was Sepp Holzer's, but when I started my internet research, I found quite a few groups who had either turned permaculture into a political weapon or made a religious experience out of it. I acknowledge that one of both of those might appeal to some folks, but it was a huge turn-off for me.

Realistically, cost is moot for me because there's no way I could afford a PDC. But if others find money tight and are comparing courses, this information would be helpful.
