What does one do, if he or she just happens to.....

Find concrete evidence that ufo's do exist? (with the exception of a government official of any kind, cause it'll disappear, lol). It can be someone that either just started wondering whats out there or a person that has made a lifes work of it. Also it doesnt matter where or how they got the evidence initially, lets just say that they have the smoking gun. Is there a office you go to, like when you win the lotto?
