Are there places in Belgium or netherlands where you can buy coffee green beans for agricultural reasons? I want to grow my own coffee tree from the seed in my home in Belgium but I can't find living coffee beans.

I went to a local coffee enterprise(Miko Turnhout) to ask for unburned seeds (green beans). They told me that their green beans are already neutralized(killed) so they don’t germinate during the transport. I looked online to buy green beans but I only could buy it in large amounts (min. 1kg) and it was very expensive because it had to travel from southern hemisphere.

Are there places in Belgium where you can buy coffee green beans for agricultural reasons? Or are there websites where you can order a small amount of coffee green beans without shipping them from the other side of the world?
For other people from Belgium or the netherlands who were searching for green coffee beans to farm. I found a website where you can buy them.
