Online league management software

I'm not sure if this is the right part of this forum... but i'm running out of ideas
Does anyone know where I could get a code or programm for the management of the online league (just to get the idea what i'm talking about www.euroslam.com)
We're running our league for the 7th season now, and we'd really like to make an upgrade

thanks for the information

Mark Nordstrom has developed a script, but it's not free. I don't know if there are any free scripts out there. I understand Mark's script is quite good if you're willing to shell out the money.
