We're looking to get hold of a posh caravan/trailer - maybe the sort that gets used on a film shoot or outside broadcast. We want to pitch it outside our office for a special team that we're putting together. Ideally, it should be a bit bigger than the one pictured above - we'll probably have to fit about six people into it

Do you know where we could find such a thing? Are there companies that hire them out? Or sell them? All info welcome...
