Hi DDD,

Thank you for your email. 

My name is XXX, and I am the administrative assistant of YYY, Esq. I am very sorry to inform you that the time you plan to consult with YYY, Esq. has been occupied 2 days ago. Does there have another time available for you? In order not to violate professional ethics, here are two questions that we need to ask and ensure before you become YYY, Esq.’s client.

1. Do you have Chinese name? If you do, could you tell us? 2. Since YYY Hsu, Esq. has established a firm conflict check system, she wants to know whether the person or the company to whom you will discuss in your case is her existing clients. 

Besides that, the consulting fee is 8,000 NT dollars per hour, but YYY, Esq. charges 7,000 NT dollars per hour for you.(charging for 7,000 NT dollars even not in one hour)

Best Regards

Hi DDD,
Thank you for your email. My name is XXX, and I am the administrative assistant of YYY. For conflict check purposes, may we have your Chinese name? I am sorry to inform you that YYY has a meeting tomorrow afternoon. Assuming the conflict check is clean, do you have any time slot next week? Please be informed that Alicia’s consulting fee rate is NTD8,000 per hour. Since you are referred by HHH, YYY is happy to offer a special rate of NTD 7,000 per hour.  The minimum charge is one hour.
