Unfortunately you won't find fresh cream as you know it in France. We live next door to a small dairy farm and can get milk straight from the cow and still warm. The cream rises to the top just like in the old days. That's probably your friends best bet.
An alternative is to order from the UK. This company do lots of fresh products including cream https://www.britishcornershop.co.uk/longley-farm-double-cream. That's not going to be a regular supply of course but an occasional treat. He will probably just have to get used to the taste of the UHT stuff although Lidl fluide creme (in the cold cabinet) is pretty good and worth a try.
