To answer the question. I've been doing GUI design for over 20 years.
To be absolutely honest. The operational level has become quite a bore. Been there, done that.
No way I'm doing this for free.
I'm more into analysis now and have several developers working for me.
Which is the natural progression of things anyway.
And as an analist designing the GUI is still part of the job of course.
I'm only saying this to be done with your stupid arguments.
