Any Direct Bus transport from Shenzhen Bao'an Airport to Shantou

My wife & I wish to take a bus from SZ to Shantou. We will be arriving by flight to Bao'an International Airport at 11am on 31Oct2012. Can u please advise me if there is a direct bus to Shantou from Bao'an Airport? If not which is the most suitable bus station to make the trip, the direction to that bus station from the Airport, the time schedules of the bus to Shantou and the average fares, etc. Thanking you in advance.
