Advantage of going to Nationals with AAU team?

Coaches,
  
        I am coaching a 7th grade team that I really feel will win every tournament in our area and thus, go to nationals.   I have a 6'4 center, a 6'0 slasher who has played TWO grades up the past years, as well as played POINT guard in the last four games of his junior high season.  That is because the BEST point guard in the area had grade problerms.   Now all of that is set aside, and I have BOTH players potentially!  I have all of the best players in the area.   Now it's just a matter of how far we can go.  Any tips on how  we can fundraise for our team to go nationals?

Thanks,
Sam Waniewski
