I am looking to get a lot of lawns in industrial buildings. I want to get about 20 new buildings. i have been wondering if it is better to go building to building with a price and kinda see what happens but i tried a few but am not sure if it is going to work. I am talking 30 min jobs here not condos and apts. Or is it best to just flyer there area a bunch of times and thinnk they will call. What do you guys find that has worked best??????
