How do I begin it?
Thank you for using the Jiskha Homework Help Forum. If you mean "how do you begin an essay" try the "introduction." What are you going to write about? The thesis statement does not have to be in the first paragraph but it makes it easy to begin.
There are samples of phrasing and wording you can use in a letter of this type. Be sure to read through the entire first webpage linked above. The second link will take you to other webpages that will help with various kinds of business writing.
