Hi !
I don't know if it can help you, but there is a letterpress studio in France, in Nantes, that could interest you.
A years ago, the prices was 40/50E for the "plaque" (sorry I don't know the word) for each color, plus 1E for each print.
You can see an example of their print there :

I don't know how much would cost the shipping + taxes in this case. But I go to France pretty often, so eventually, if you want to work with that studio, you can ask them to send your cards in a post office at the french border, and I can pick it up when I go there....
Let me know if you are interested !
I would be happy to help, I am a letterpress enthusiastic ! And if someone knows if there are letterpress studios in Zurich and around, I would be interested to know too !
