Anton,
I knew of a place but couldn’t find their name so I did some searching and found a couple places that might work for your friend. My google search was “personalized custom embossed foil wine labels”
This place >> www.bottleyourbrand.com/custom+wine+labels+gold+foil looked relatively easy to customize a label.
There were several other places listed too. mavericklabel.com had some really nice ones but minimum was 250 labels. There’s also Vista Print but not sure they look all that great.
