Wow! A unique idea, for a change! At least, I've never run across that one before.

I've been through enough training pipelines in the Navy and in civilian life that I can see some merit in what you're proposing.

Normally a corporation will evaluate its training process from 2 different vantage points:

(1) From on high. That'd be the stoic gentleman with the clipboard standing over the instructor's shoulder. But he mainly just reinforces past standards rather than looking for novel improvements.

(2) From the bottom up. Feedback from students after the fact. But their focus is learning material and courting favor with the boss. That's very different from an independent evaluation of pedagogy from someone with wide comparative experience.

What you're offering is quite different, and it's important to explain your function to people who probably have never imagined it.

The best way to build the business would be to volunteer to tag along for a few of the shorter training cycles, help a few companies for free, and build a portfolio of success stories to point to. They might also refer you to paying clients or hire you in the future.

When it comes to choosing a brand name or explaining what you do with written copy, I can help. I'd enjoy helping this idea take off and pointing to it as a success story.
