Startup Idea : Local basketball league (results and stats)

I’ve been in local basketball leagues almost all my life, and I’ve notice one small problem, it’s hard to keep track of all the game results during the season. I would like to bring an end to this by creating a local basketball league webApp were each league that is signed up will have all participating players, results from games (score, player’s points, assists, rebounds etc.) and their averages. If done right this can be huge there are hundreds of basketball leagues in the states alone, searching for game results and your own stats will never be more fun! I know HTML5, CSS3 and a little of Javascript I am still learning.
