Buying Whole Grains in France and/or Tahiti

I have just bought a mill and am excited to start milling my own flour, however I have been struggling to find an online retailer for whole grains in France. Does anyone order whole grains to mill at home in France? The couple websites I have found won't ship to France because of Brexit. I do not speak French so maybe I am not searching for the right name because of the translation? 

I will be in Tahiti next year and will need to buy whole grains there, so while I'm here asking, does anyone know where to buy grains in Tahiti? 

Thank you in advance for help in finding whole grains I can start milling at home. Very excited!
