I get where you're coming from, I do these types of engagements often. I just wanted to highlight the difference between "Please spend $25,000 on this pentest engagement" and "Don't set a maximum password length of 10" or "Don't set the default password to be 6 digits".
One is an investment and requires convincing a PM or C-Suite. The other two are some of the most basic concepts possible (literally first semester, if not first week of CS) in the design of anything that has to do with a password.
