I need help with this assignment.

 Your last assignment is to video tape a role play dialogue/sales call video presentation using a family member, friend or classmate. Your video presentation should show what you have learned as you try to sell your buyer a product or service of your choice, and there is no time limit on the video. (Review chapters 7 & 8). 

 I want you to write me like a text what to say both as buyer and seller and you decide which product/service too!!!! I will record the video by myself,just need the text.

I also posted the chapter 7 and 8 it might help you.
