Hkia to Shekou port by ferries, but how?

I buy air ticket of United Airlines, so could i take ferry from Hkia to Shekou port and vice versa ?
From Shekou port, how long does it take to arrive SunShine hotel in Luohu district ? And how much does it cost to catch a taxi from Shekou port to the hotel? Kindly advise me soon with many thanks
