Dear Mr. Grace,

亲爱的格雷斯先生：

We regret very much that we are unable to postpone the fixed date of our appointment, because we have another client who is quite willing to cooperate with us.

An early reply would be appreciated as we wish to reach a prompt decision.

很抱歉，我们无法延后我们订好的约会时间，因为已经有另外一名客户很想跟我们合作。本公司希望能尽快下决定，故请您尽早回复。

Yours sincerely,

Paul Walker
