We used these guys last year: http://europeremove.com
to get our stuff from London to Zurich.
Reasonable price, and pretty quick (think it was something like 5 days from pickup in the UK to dropoff in CH). We had less than 1 van's worth, something like 15-20 assorted sized moving boxes. Did the packing ourselves to save on $$.
Price-wise, by the time you pay for fuel/tolls/ferries etc, would probably work out pretty close.
