Developer Name

How do you get an organisations name to show up as the 'Developer' of an app - rather than an individual? I'm a little confused by the various developer sign-up options and would appreciate it if someone could explain.

The reason I ask is that I run a few websites with a group of friends, totally none-profit, we're obviously not registered as a company or anything, but it would be nice to have our domain name as the developer - good publicity and we could perhaps release a few related apps that would show up under our name.

Any help would be appreciated
