Tournament Bracket Generator

I need to create a bracket generator like [login to view URL] where i insert any amount of teams and it generates the bracket dinamycally based on the amounts of team, without having many empty brackets. The number of teams is unlimited, i add the amount i want. Also it must save on mysql database all matches and incoming matches, rounds, team id and score The code must be simple, or atleast must be a class so i can develop easily the stuff. Must generate the same brackets css style like [login to view URL] Ill give this work for someone who already done something like this, if you did a bracket generator please sendme pmb with a demo. Thanks.
