what is right rate with a Chinese legal+commercial background?

Thanks for looking!

From my profile you can see I have Chinese legal and commercial background. My really value is my Chinese expertise in legal, commercial, network, language and culture background.

for pure legal assignment in China,I would charge 120-180euro/per hr . Is it a proper one?
for the pure purchasing in China, I donÂ?t mind set my rate around 75-90. Is it a friendly rate?

However, sometime these two activities are mixed, and then I am confused how much rate I should set up.

Any comments and suggestion are deeply appreciated.

Here is my profile

I am 41 years old, female, I am a qualified Chinese commercial lawyer and experienced buying consultant. In my 14-year career in China (1987-2001), I served as a court official and commercial law judge, as a contracts and dual-diligence specialist with a Shanghai Law firm, and as an import-export consultant. I came to the NL in Oct. 2002. First I studied at Utrecht University to obtain the master of law and economics, then I have worked as a buyer and contracts advisor for Dutch companies importing from China, and as a legal advisor of the China desk at the Amsterdam Law firm.

To expand my opportunities in relation to dealings with China, I recently established my own freelance company SourceLink-China NL, aimed at helping Dutch companies to:
-locate Chinese business partners and suppliers
-set up appropriate agreements and contracts
-conduct dual diligence investigations
-achieve optimal pricing through direct contact with manufacturers
-guarantee conformity with quality standards
-minimize financial and legal risks.
