Go a step further, write some company blog posts outlining how to do it yourself. Do a good job, honestly show how easy it is to host your own alternative, you're making the world a better place by doing so.
You want readers to think "that would be easy, maybe I'll do it". They start to believe it's important they have what you're offering and they think they'll do it themselves.
Well, we know how attention spans are these days, if something takes 30 minutes of work it will probably never get done. Most of the people will give up, and a lot of them will buy your hosted service instead because they've already convinced themselves it's important. If it's important enough to someone that they would spend their time on it, they'll spend money on it too. You want people willing to spend time / money on something to have good will towards your company.
