Everything in the guide comes down to a handful of checks you can run before you pay. None of them takes long. Together they take about five minutes, and they are the difference between booking on evidence and booking on hope.
Print this page, screenshot it, or copy it into your notes. It is meant to be used, not admired.
"Know who you are paying, know what you are buying, and know what an hour of it is worth. Almost everything above is a longer way of saying that."
This guide tells you not to take claims on trust, so here is the checklist from its last page, free and without an email address. If it is useful on its own, the 39 pages behind it explain why each item is on the list — what a bad answer looks like, and what the benchmark figures actually are. In the PDF every item also carries the page number of the section it came from, so the checklist doubles as an index into the guide.
