I was given this link to give a survey for one of your providers, Earl. 

1. He was patient

2. He had a great sense of humor - a very important component when servicing clients. You should bottle his style and sell it. Give him 5% of the profits.

3. He fixed my challenge and even provided a couple  "hints" to keep me aware of the realities of Proforma.

4. I recommend him for a raise. He's worth every Nickle and dime.
