Advertising on Commercial property suggestions (grass lot)
My family and I have commercial property that used to be residential. The property is just a grass lot that sits near an expressway. We are still trying to figure out what do with it and I think it would be great for people to advertise their businesses and a way for us to make some money. Anyone ever did this? Also do I just put out a sign that says to contact us if interested in advertising? 

Help.
