Just another thought is to see if anyone else on the forum/community can help drive it across, daisy chain.

https://www.shiply.com is an shipping quote site I've had good experience with where you submit the job and company's bid for the work, it can throw up some good prices and if you get a MIV you may not need to package it all up. But i'm not sure what prices will be internationally as I've only used it domestically.
