Dear xxxxx,

I am very glad to receive your enquiry email.
We supply interpretation services, including simultaneous interpretation and  consecutive Interpretation.
The rate of English and Chinese simultaneous interpretation is about USD xxxx per day.
The rate of  English and Chinese consecutive interpretation is about USD xxx per day.
I think your need is  consecutive Interpretation between Chinese and English, because you only need an accompaning interpretor during your business meetings.

Please give me a confirmation. You can search on www.google.com  to find the meanings of the two different interpretation services.
收到你方询盘，我很高兴。
我们提供口译服务，包括同声传译和交替传译。
英语和汉语的同声传译费率是每天约XXXX美元。
英语和中文的交替传译费率为每天XXX美元。
我想你需要的是中英文交替传译，因为你只需要一个商务会议陪同口译。
请给我一个确认。你可以在Google搜索引擎搜索找到这两种不同的口译服务的定义。
