Sightseeing in Guangzhou - long connection

Hi, I am travelling with a few others and arrive the airport at 6am on 29 June 2013 and my connecting flight is at 11:55am.

Are there any local sightseeing options that could pick us up at the airport with an english speaking guide, take us to some sights and a restaurant for lunch and then some more sightseeing, then dinner and back at the airport by say 10pm?

THanks!
