Hire a bunch of solid case bike boxes from the likes of http://www.bikebox-online.co.uk/ and then drive them in the back of a luton or similar. Or you could even do the rounds of bike shops and take their old cardboard bike boxes.
Or you could look for a company similar to http://www.libertycoaches.info/ who might have a large volume bicycle specific trailer available for hire.
