You might consider trying the Rohkost/-Instinkto community in Germany. Most of them go in for 100% vegan diets but a few do go in for raw eggs and raw dairy, and a tiny few might go in for eating raw meats. Also, there is a website for finding local weston price chapters in international areas but the site is down for now.
Otherwise, search local farmers' markets and ask the relevant farmers what they feed their animals on. Or check any online organic food directories for local shops selling organic meat, they might provide grassfed meat as well. Or look around for a shop(or preferably) warehouse selling raw wild game.
Of course, some of those who cannot find suitable grassfed meat do go in for raw wildcaught seafood instead, but that can be expensive if too far from the coast. At any rate, my own experience indicated that, for me, raw wildcaught seafood should never be above 50% of my diet, and preferably not less than 10%, if possible.
