One way Minibus Hire - 3 Peaks Challenge

[Muncher]

I'm doing the driving for a team at work who are doing the 3 peaks challenge in June.

What I'd like to do is hire a minibus at Glasgow airport and return it to a London airport ideally. However I'm struggling to find anyone who offers this kind of service.

I'm trying to avoid having to drive from London to Glasgow just before the event begins as I'll have enough driving as it is and would rather cut out that treck if at all possible.
