At this scale the question is not what it costs but how long it lasts and how you reach it. The same wall can carry perforated vinyl, a painted system or a steel-framed tarpaulin face, and those three answers have very different technical lives. We quote them as separate options with their own access plans rather than pretending there is one right answer.
