It would take someone far braver than I to give you a name. A forum like this isn't the place for that. Much better you ask around personally in HK and get two or three names. To repeat, it will not be cheap!
You'll also want some advice about HK taxes. Especially if you'll be travelling on business outside HK a lot, there may be some HK tax advantage in structuring your initial employment agreement in a certain fashion before you arrive HK.
I did not mean to ask for a specific tax consultant but a company that does this... I don't know too much since my US taxes have never been so complicated.
My work will not involve traveling outside of HK.
