Oh clients. They aways want stuff for free. But in the real world that's not how it works. The short order cook behind the counter asks "When's the last time you got something for free?" Before answering "You must work for the government." Truth in advertising right there.
While this is great self-promotion for Zulu Alpha Kilo, I'll bet a lot of clients who might go this route are going to be turned off. Come to think of it, does Zulu Alpha Kilo pitch business? Because if so, isn't that basically working for free?
