Answer:
The letter could be somewhat like this:
Dear Hank White, CEO of Great BBQ
I am John Smith, I am the CEO of a meat distributor. I specialize in prime cuts like New York Ribeye, Tenderloin, and Wagyu Beef with the best Japanese Technique.
I am sure that as business partners, we both could do better than we do right now. I have the best raw material for your restaurant business, and you have the BBQ expertise and knowledge.
I would appreciate if you considered this letter, you can call me any time if you want to discuss further, or write me an email-.
Sincerely
John Smith
