Chloe I have a server for 10 month on fat cow unlimited bandwidth ...just needs a domain name. You can have it . You just need someon in teh know to set up several insrtances of shoutcast server so we can have a load of listeners I think....I did have a 3 month contract on a shoutcats server...50 listeners @192 and that was abut 60 quid.
Its simple, this stuff don't pay for itself at all, I am willing to support it, but I know organising 20 Dj's to log in and out on time is gonna be a lot of work. DJ's are a special kind of stupid. they forget how to stream, what their names is, they decide they can't be arsed. Its a thankless task, but don't let that put you off.
basically won't happen on your own.
