I am writing to let you know

I am writing to let you know how pleased I am with the work you did.  I went over yesterday to inspect it.  Everything was done exactly according to the specifications, and it was finished very neatly.  Your work throughout the whole suite was above par.  It was a pleasure to have such a good job done and to have it done ahead of schedule!  My final praise is for leaving the place completely clean and ready to move in.  Thanks for a job well done.  I will definitely spread the word among my acquaintances about your good works.
