I take on a few projects a quarter and read every brief myself. Three questions and your name are enough to start. Concrete beats polished.
The thing, in a sentence or two. A site, a product, or a fix for something that keeps breaking.
The people who will use it, and what they need to get done there.
A budget, a range, or what it costs you every month it doesn't exist.
Your name, and the business if there is one.
