When I moved over here with Frau Indoors, we brought all that we could carry on the plane. Large rolling bags for under the plane and full amount of carry-ons. Weight limits were almost reached.
Taxi is needed at both ends if you are doing it alone. You also can look into flying over with extra bags that you pay for. Some small fee like 50$ or 75$ is much better than trying to ship it. Plus if you are really cute customs might leave you alone!
Then put your stuff in storage or with a friend, bring back the empty bags, and do it all again.
-Of course it only goes for packable stuff. Good luck with everything else.
