You are afraid of the number. Most sites land in the low forties, and the bottom band is a content problem. Request the score anyway.
What if your score is bad? Then you have a map. Most law firm sites land in the low forties out of a hundred, and the bottom band does not mean anything is wrong with your firm. It means the trust architecture has not been built yet.
In almost every case, the first fixes are content changes inside the design you already have: a price near the button, three steps with time anchors, a stated response time, a real face above the fold. The report tells you which one comes first and why.
A low score is the most useful thing a week can give you. A high score is good news. Either way, you know.
