Greetings to you, and yours!
Though your description of the project is brief, it contains great appeal for me! To write in a given persona would allow me to indulge both my writing ability, for which I am known, and also my heretofore secret, passion for theater. If I understand you correctly, you will describe to me a person, and then I will prepare the content you require, written as though I were that person. I am thrilled at the prospect!
The task of understanding the corporate profile, and using language suitable to the project, poses no difficulty. I have studied corporate law, and understand that language. Additionally, throughout the course of my professional career, the use of language, both to influence and impress, has been a recognized skill of mine.
I have no doubt that, should you choose to employ me for this project, we will both be glad of your decision!
With great sincerity,
Patience V.
