CHINESE email addresses

We need many many email addresses in China, preferably Beijing but any email address is welcome. Any quantity is welcome. Good quality address obvioulsy important but in any way we would want to test. The persons need to live in China. We want to use the address to send a serious invitation once for a free IQ test. Budget depends on quality and quantity. It should be around 1000 RMB per 30,0000 emails.
