I doubt you will find any yard here with much IP experience. We are somewhat rare boats in Europe. However, I do know of an in general, very good and reasonably priced yard here in Spain, they do alot of custom work so could probably handle that job. The manager is a Brit, so no language problems. Take a look at Almerimar, near the town of Almeria in Spain in Andalusia. They have a pretty good website:
