Edible transfer?

Hi everyone,

I’m after a bit of advise. I’ve been asked by a friend to do their wedding cake, they’re wanting the Barcelona skyline to go round one of the tiers! The only way I can imagine to do this is to get some kind of edible transfer but I have no idea where from? Does anyone have any suggestions? Or any other ways of doing it? I can’t paint if on by hand, I’m no artist!!! Any help would be appreciated
