During a virtually rain-free June, I got a few calls wanting an estimate for an irrigation system. Most of them have no idea what to expect, so to weed out the tire kickers, I ask a few questions re the size of their lot, how many flower beds, and give them a ball park range. If that range seems to be in their budget, I offer to go out and measure and do a design and bid. How are you guys handling these type calls? How far do you go before you are willing to spend the time to do a drawing? (Assuming you do drawing).
