What is the rate for leasing outdoor advertising billboard or signage space on a commercial building property?

Bill Boards start at $5000 per month plus the signage
banner postings on a building depend on where the building is located , how big the banner is nad how long the city will permit the posting to hang there
In Miami it starts at 20K per week and can go as high as 100K per month plus permit fees and the cost of the banner
