I think it's actually a lot harder to be clear than it is to be superficially clever. It means you really have to work to define your audience. Not an easy thing.
I understand that it's a different role, hence my interest.
I'm not sure I agree that a contractor is there to merely practice his craft, compared to the consultant who is there to make sure a company in a better position than before. It should be a contractor's job to do that as well.
This is why I'm seeing quite a grey area between what constitutes a consultant, and a contractor, or freelancer.
I'm currently looking at a few opportunities and am actually launching a workshop next month. I dont want to link to it yet, as it's currently only available for folks who bought my book. However, it's an area that I'm interested in expanding upon.
With regards to Luke and Gabriel, this is probably more the area I had in mind when writing my question, it would be quite interesting to develop something more along these lines, it would certainly take me out of my comfort zone.
Thanks again Charlie, you've given me some food for thought.
