A computerized system includes a central site with various databases and a user site connected for electronic communication over a networked communication system such as the Internet. The user site includes a computer having stored in memory an application that enables a user to develop a construction proposal including a detailed graphical model and a detailed cost estimate model, have the proposal submitted electronically over a networked communication system to a construction professional for a bid, and receive a response on the proposal from the construction professional over the networked communications system. The user accomplishes all of these tasks from a single computer environment. The application educates the user as it guides the user through a series of construction phases and steps, prompting the user to input critical information and make appropriate selections throughout the series of phases and steps.
