I have a small house with a major freeway behind it and a major four way street in front. I am interesting in perhaps renting out the space over my house both in front and back, for billboard advertising. My house is on commercial property and several others around my area have billboards and none of them have near the advertising potentional that my house has. How can I go about this and can anyone tell me possibly what the going rates might be these days? Thank you.
