BaseTwits for Youth baseball

I invision a way for parents, coaches or whoever to be able to give people at home updates on youth baseball games. It can be based off the twitter API. I would like to build my own messaging service and be able to log in with twitter versus being dependent on twitter. I would encourage coaches or leagues to get on and register their Team Name and city, and maybe another qualifier like their division. Then people can get on and follow that team, just like you follow friends on twitter. Parents or coaches at the games could update scores for that team and others who also follow, could comment, like "great game!" or "good hit" or any other highlights they want to add from the game. (Coaches would also be able to post info about practice times, tourneys, etc and the people who follow the team or the coach would be able to see them and leave comments.) Kind of the Twitter mentality, geared at parents, scorekeepers, coaches to write their own updates and highlights about their kids games for others. These score and highlight updates could be tied to Twitter and have a corresponding website. Any suggestions? I would like a ballpark fixed price for the total job. Very simple idea, just a way for youth game scores to be posted by someone at the game. The website would just be another way for people to sign up to post comments and follow teams, in addition to posting and following on twitter. Similar concept to how [login to view URL] uses Twitter and has a website. Of course my website would not have near as much info, just a portal to access if you were at home on a computer and not on the phone.
