Haha. You might think you can do it that cheaply. And in a sane world I'm sure you could. But this is the government you're dealing with. The requirements list should fit on one side of A4 but will instead fill a large binder. The requirements will change every couple of days while you're implementing it. It'll be the never ending project.
Perhaps the game shooters weren't that important so it just got done. The politicians and the media are drone obsessed, cos terrorism, so everyone will want to meddle with it.
