Abstract: A system for preparing and presenting a proposal at a property utilizes wide-area networking to retrieve an aerial photograph or satellite image of the property, onto which a sales person indicates the locations, types, and specifications of fixtures on the property that are available for upgrade/replacement. Once the image/photograph is complete, the system accesses current pricing and installation costs for the fixtures and generates a proposal that is provided to the property owner. This system provides for a single visit to a property to gather fixture location, type, specification; generate proposals; and seal a deal with the property owner. Since the replacement fixtures are more energy efficient than those that are existing, the proposal utilizes local energy rates to determine the amount of time before the replacement fixtures pay for themselves in reduce energy consumption and cost.
