A dedicated portable computer sales presentation system for efficiently making a multimedia sales presentation at the location of a customer. The dedicated portable computer sales presentation system includes installing the required sales presentation files upon a hard drive of the portable computer system, blocking access to the Internet from the portable computer system and removing a media player from the portable computer system to allow the portable computer system to only be utilized for making a multimedia sales presentation to the customer. When the sales agent meets with a customer, the agent calls the company and answers a series of introduction questions relating to the customer and the call is terminated with the company recording the end time of the call as the start time of the sales presentation. The multimedia sales presentation (which may include a virtual tour run from the hard drive) is made upon the portable computer system and if a sale is made the necessary contract is printed for the customer to sign. The sales agent then shuts down the portable computer system and then calls the company to answer closing questions where after the call is terminated with the company recording the start time of the call as the end time of the sales presentation.
