This letter is a follow-up to our phone conversation last Friday, March 12. I need written authorization so I can act as your representative in securing a location for a new office in this city. As we discussed last week, I will select three possible sites that you can inspect next month.
As soon as I have confirmation of our agreement, I will begin my search for an appropriate location for the new branch of the Doe Corporation. I have enjoyed our telephone discussions and look forward to meeting you and showing you around the city next month.
