There is a minor chance it will get lost overboard or stuck in a canal. So you should arrange specialist insurance.

The reason everyone wants to give you a personal quote is that end users are unreliable. And you don't know how things have to be packed. And you don't know how much free space there is on an upcoming ship. And you don't know how easy your home is to get a shipping container to. And... It goes on.

I'd start by looking at expat forums and seeing if people have decent/recent experience with a company.

But… unless this stuff is either expensive, irreplaceable, or sentimental - you're probably better off selling it locally and buying replacements.
