Help with shipping

Can anyone give me a idea on who to contact in order to ship my glider
from Seattle, WA area (or maybe Portland, OR) to Bremerhaven, Germany?
I ran into a brick wall. I want to ship my glider with my trailer, for
ease of transportation here and in Europe. Some of the brokers want me
to remove the glider from the trailer and ship it separate. I can not
explain to those guys what a glider is and they don't see the concept
of a glider trailer. They all are thinking it is a hang glider.
Please call me at 509 380 4106 (my cell) or email jacekkobiesa at
raypoland and sons dot com (everything is one word without any
spaces). So, if you have any idea on who to contact, please help.

Thanks for your help.
