howdy! well, we r in europe so do not have direct experience with us importing. (or importing into europe, for that matter!). all i wanted to share was that there is a guy named Tobias (i think) who i believe has this website
ORCHIBIAS - Orchids for Europe
i have received orders for somebody in the past who went thru him. the plants were all in great condition and all easily survived the winter in our flat before we shipped them to their true owner. and they were expensive, so i can only guess the import fees are large. but just sharing cause maybe you reach out to him and ask him for some input. he has emailed me back quickly in the past. good luck!
