When I was looking for cabs around europe, I just contacted my local truck company / dispatch departement ( spedition in german ). But well, it would costs a bit ( for example, I paid about 170,- from berlin to upper austria = 600 km over CZ ). And the cabs must be well packed on an euro palette ( which shouldnt be a problem when you send it away ) and the package would be picked up only on ground lvl ( entrance area ).
