Has anyone had a galvanized or metal roof installed on their house lately? How much?

So we have a really old roof. It is aluminum shingles right now. It is leaking and we need work done. I was thinking about having a new roof put on that is single sheets of metal. Like a galvanized, aluminum or tin roof. But I can not find any prices online. Has anyone had one done recently (Louisiana area)? Can you tell me how much it was?
