Both of these companies have indicated that they can
do the courses in English, but at additional cost, and probably one-on-one (due to low demand): www.microwin.com www.digicomp.ch
I think they both have locations in Zürich. I emailed both of them Friday, asking about pricing, scheduling, and available locations, which I'll be happy to pass along when I get my answers, if you're interested.
We might be able to save some money, if we could arrange to take one or both courses at the same time. Please PM me if you're interested in trying that.
