Sample D
Dear Mr Morgan,
Thank you for your letter.
I beleive there is a great opportunity for us because the delivery company we'd been working before has gone bankrupt, so we're looking for a new one. Let me explain what type of goods we usually need to deliver. We run a small on-line shop in the Internet offering different types of hardware like personal computers and various networking eqipement.
Currently we're expanding in the local market so we're interested in a long-term partnership with a delivery service, like yours. Could you please think of a suitable day to visit our office?
I look forward to your reply!
Best regards,
Mr P,
CEO
