Start aconversation.
Coaching, advisory, a keynote, or something you are not sure how to categorise yet. Thirty minutes is usually enough to work out whether there is something here.
Before you write
It helps to know the situation, not the category.
You do not need a brief. One paragraph about the actual thing that is happening, the person or team involved, and what you have already tried, gets us further in thirty minutes than a job description would.
