World Cup Sweepstake online?

Hi,

Anybody know of any online sites where you can add your own names and teams and it automagicaly works out the standings during the matches?

For instance - work want to do a sweepstake and it would be fun to have online managment of it - i.e. Fred has picked England and Brazil, Adam has picked Italy and USA etc and as we go , the scores are added to the teams and gives the results etc?

And only the sweepstake players can access the page...
