We are setting up a new take off and want to share it with a client in the form of an excel file preferably or in the form of a proposal.

This is for a new house.  Our client wants to see a base price as per the plan provided and then alternate options.  For example, he wants Marvin Windows to be in the base bid but wants to see how using Andersen windows would affect the bottom line.  We have many options for him in many different categories.  We would prefer to keep all of the information in one place in the MB take off and not have to create a separate report on excel.  How should we organize our take offs to make this easy for our client to understand?
