Hi Faye,
I'm not in Zurich but I might be able to help you. (The Swiss postal system is fabulous; and my husband and I are planning a trip to Zurich in a couple of weeks if you wanted to meet personally). I do letterpress work on 100% cotton papers and gorgeously thick card stock using an Adana 8x5 hand press. I have a photo polymer platemaker so I'm not limited to using metal type and now can also do die cuts/ small packaging runs etc.
My blog has some of my work up (

Thanks Carlos R
