trust companies

I'd like to open a limited liability company here in HK, and had a look through your site, but surprisingly didn't find anything (maybe my search wasn't complete).  I've had a look at the Tax department and the company registry sites, and it seems to be relatively simple, but, having owned businesses in other countries I know it is often better to do it through a trust company or accounting service who then does your secretarial, legal, tax and accounting stuff for you.
