I have an invention . but what to do next ?

Hello everyone I am a new inventor and I have an invention ,it`s a new device for building fire escape , and now I am very puzzled because I don`t know what to do next .Though I work hard to try to promote it ,but so far it still seems hopeless . Is an invention really a nightmare for one poor inventor? Are all inventions always "fool`gold" for inventors ? What shall I do ? http://jinshi.selfrescue.googlepages.com/
