Dear Anthony,
You were originally right. I am impressed with your abilities, your work, your price, your response time, and your communication. If you ever need a reference, you are free to use this quote and my name; I live in Texas and am retired engineer, actually manager since age 28. Also, I would be glad to write another note or take a phone call from a stranger about my experience with you. I am a retired widower, age 65, so a phone call now and then is no biggie for me, I rarely get them.
Again, thanks for a job well done and I look forward to getting the last request I sent. I know from experience that I will likely not need a strategy nor another indicator, but if I do, you are the man I will contact. Again, thanks!
Best Regards,
