"I wanted to thank you for your efforts. Out of all the agencies I contacted you were by far the most helpful and went out of your way more than any other. I was extremely impressed with your commitment.
I will definitely keep you in mind for future reference if I were to need another job and will be recommending you to any others I hear that are looking for work in insolvency as I can guarantee you will work hard for them.
Once again, thank you for your efforts."
