Dear Mr.Thompson：
I have enclosed a copy of the evaluation that I was hired to prepare for the project ’Improving Employee Performance.’You will see that the evaluation is divided into three sections，as we agreed upon in our discussion：Employee Relations，Physical Environment，and Training Opportunities.The appendices include all forms and outlines of other methods used to gather information for the evaluation.I have attempted to present everything in as clear a manner as possible.If，however，you have any questions or desire any additional information，please don’t hesitate to contact me.
I have enjoyed working with your law firm on this project and look forward to working with you again in the future.
Sincerely，
Amanda Guess
Consultant
