Jason's comment (as well as others) is spot-on. It's only a project. However, projects are how many sustainable businesses begin.

Your project is based on your assumptions on what customers wants. You now need to discover whether those assumptions are true (facts) or completely wrong. If they turn out to be true, then you're on to something.

Don't give up. Even if your assumptions turn out to be wrong, 'failures' are part of the process, and you can use what you learned on your next quest for a sustainable business.
