How far out do you guys find that you can book residential hardscape projects. I'm talking about during the season, not booking projects in January for April. Last year was my first full year running my business and I found that I hit a wall at about six weeks. Potential customers didn't want to wait any longer. I'm thinking that as I begin to sell "word of mouth" projects, I may be able to stretch it out a little further. What have your experiences been?
