Need Shipping Company from Europe to Asia

Hello,

Does anybody know a reliable and reasonably priced shipping company that can transport large quantities (~1.5m^3 / Protected content from Germany to Thailand?

Initially, I wanted to use Intercargo. Their estimate came out to be Protected content for Air Post / Protected content a Freight Ship, which is doable. However, after reading some reviews, I no longer feel that this company is trustworthy.

DHL meanwhile came out to over 2,500 Euro for individual packages (I have 11 of them), and their Maxi Transport only offered up to Protected content .

I still believe that a Container would be the cheapest option, but I need your help to find a good company.

Thank you
