Does anyone have experience or knowledge of shipping Meridian gear using Cash on Delivery into Germany from UK?

I am exploring a potential sale of my London based DSP8K to a buyer based in Germany. He would like cash on delivery (COD) but most logistics companies we looked at do not do more than a few thousand in COD.

Thanks in advance.
