Best way to register and manage sporting teams?

Hello!

I am working on a website that will allow team captains to register for a sport, pay using paypal, and anyone will be able to view team schedules, standings, and team stats.

I’m hoping someone can suggest the best way for me to manage schedules and teams, and here’s where I’m at so far.

1) I’ve played with both the events espresso and events registration plugins, and both can create events and accept payment.

2) I’ve created tables in my database to store the teams, players, seasons, and games.

3) Every time registration is over I can manually enter in those teams who have paid through phpmyadmin into my tables.

4) I can display the schedules, standings, and team stats using the WP-Table Reloaded plugin, but first I must export from phpmyadmin and import a .csv into the plugin. This is the step that seems could be improvded.

In a perfect world, I’d like to get a list of registrants that have paid, copy those over into the teams table, and then have a plugin pull data directly from the same mysql database to display the tables on my pages.

Any suggestions at all would be appreciated. I might in the end just try to figure out how to make my own plugin, so if you have some similar examples, I could take a look at the code for those as well.

Thanks!
Garrett
