How can I get a volume license for FCP7?

I'm working for a production company in London and we are looking into buying FCP7 volume license. Could anyone suggest where we could do so and a contact for someone who can help?

We are not upgrading to Final Cut X and downgrading to FCP 6, since we are already set up with FCP7 and the features it has are by far the best options for what we need.

Thank you for suggestions
