Researcher to find company to incorporate new Ltd in Hong Kong

I am doing consultancy in Mainland China at the moment, and need to invoice from a company in Hong Kong. There seem to be hundreds of businesses out there who offer incorporation services, with a broad range of prices. I need 1) the best possible price 2) a bank account to go with the new business 3) to do this remotely (I am based in Beijing at the moment, and can go to branches here for ID verification if needed).

You need to research the companies, get the confirmed contact details of someone who can deal with the process and send me the information for me to verify. You will have 4 days to do the research, which should be plenty of time.
