I apologize for not having responded to you sooner. I know that the important plans you have been contemplating depend on my answers, and I am truly sorry that I haven't been more helpful and responsive.
In your letter you mentioned that you were considering expanding your business into South Korea. In answer to your question, I would be happy to offer whatever advice I can with regard to customs procedures, government policies on foreign investments, market predictions, cultural barriers, and the like. My previous experiences dealing with South Korea have left me with such a wealth of knowledge on the subject that I hardly know where to begin in a brief letter.
I am enclosing a packet of information available from the embassy, along with various other leaflets and flyers I have collected in my travels and business dealings.
Why don't you call me to set up a lunch so we can go into greater detail?
