Dear Keith,
Brenda and I would like to thank you for the wonderful job you did in designing and installing our water feature. The creative landscaping that you incorporated around the pond enhances the overall appearance of our backyard. At first I was apprehensive as to the outcome of the job. You reassured me that we would be one hundred percent pleased with the job and you were right. Once again thank you, and don't hesitate to use my name for a referral.
