Dear Mr. Scanlon,
I would like to thank you again for your cooperation and generosity in helping us out of a very difficult situation. It is not often that you will find an individual and/or company that will go out of their way to help someone as you did, especially on such short notice. Your quick response and quality work allowed us to continue our molding operation and supply a customer that was out of product. I have made everyone here aware of your efforts and we are all very appreciative.
Once again, thanks for your help!
