Darts, Pool, and various game leagues... D7 Mod?

Is anyone aware of and decent game league management scripts?  I have been Googling my ass off for months trying to find something for Dart league management, and/or pool league management.  I found a few php scripts that were designed for European soccer league management, but in literally hundreds of hours of searching over the last 6 months, I have uncovered nothing.  There seems to be a huge void in the area of game league management scripts.

Needed features:

• Online player and team registration
• Paypal payment of dues
• Auto schedule builder
• Weekly matchups
• Standings
• League news, etc.
• Ability to run unlimited leagues simultaneously.
• Discussion forum

There's more to it than the above list, but those are the basics.  There doesn't seem to be a shortage of websites where you can pay a hefty fee to use their online league management tools, but there is just nothing out there for people that want to set up their own site.  I know enough people in Houston running dart and pool leagues, to get hundreds members if I could offer something like this. 

Some of D7s built in functionality could probably be used, but this would be a pretty complex application.  That's why I asked if anyone knew of something that could be built upon.

I did something like this for a bowling league back when 6.1 came out.   I too had a hard time back then finding anything within php to do this.  There where a few script but they had been written in asp.net.

If i come across anything i'll post some links for you.

There's nothing out there.  Half the search hits I look at, lead to a link farm or a defunct sourceforge project.  Any hits that turn up something real, lead to soccer league management stuff.  I don't know about other parts of the country, but in Houston, dart leagues and pool leagues are everywhere.  It's hard to believe there are no web based management tools available.   It doesn't take long to find some PC software to manage a league, and some of those programs will output some bloated html code for schedules, results, and standings, but that doesn't help me any.

Yeah alot of excel and other formats.  I found a few desktop apps as well but not to much in the way of php.  I did find one desktop app for pool but it does not seem to work with 64bit and well its for the desktop....

I found something that shows a little promise.  It's a php app for a dart league.  It's going to take a while to sort out though... it's in Dutch.

That's nothing. I once had to translate all of Comsenz's products into English. Their language system is a mess (hundreds of template files with hundreds and hundreds of language keys, in Chinese).
