I am not really sure what you are asking for here, setting up a league file is very similar to a solo league, uploading files is a breaze & since you have a webite already i assume you know how to do that. You will need a forum and all the stuff that goes along with online leagues.
I spent a good 6 months of planning when I started the CLB so don't expect this to be a quick or easy process,. a well managed league takes time and effort to set-up and run. If you would like to talk about it send me a PM or email and I'll be happy to try and help.
