Adrian,
You may be right, 99% of golfers may not have heard of Tom Doak.
My hope is that someday potential members and property buyers will evaluate the course based on its' merits, or perhaps who built it, but based on their reputation as an architect, not a player. Definitely not a reality yet, but one can dream.
As far as setting absolute #'s, who are you to set the figure?
$500,000 to design a course in Mullen Nebraska might be more than reasonable.The whole budget might be $2 million.
$500,000 in the Hamptons might just be the cost of your seasonal rental.and the budget might be $100 million.
What if I paid an architect $1 million and he showed me a way to save 2 million? (or 10 million on a huge project)
let the market dictate fees.
