On Mac, is it possible to generate a folder structure in Finder's contextual menu?
You could use Automator with a Shell Script action. You can set it to take in "Folders" and use the below code (change the Shell Script action to take arguments instead of stdin).

cd $1
mkdir "[--] Unnamed Client"
cd "[--] Unnamed Client"
mkdir Fonts Photos Quotes "Raw Files"


The script moves to the folder you selected (cd $1). It creates a folder for the client and cd's into it. It creates folders for the contents.



If you're always making the folders in the same place, you could remove the input or change it to "Files and Folders" and change the first cd command to cd to the location where you want the client folder.
