I am looking for a Hotel / Motel or hostel in Hongkong ?

Dear friend ,

I am going from Guangzhou to Hongkong by bus on 7 Dec 2011 and will stay there for 2 days (1night) , So i am looking for a single room to stay , I would like to have a single room ,I dont want to shear my room with any one but I dont want to pay more than 200 HKD.
Can you help me ?
Even if you know a package for 1day sightseeing , then I would like to join them as well.
Thanks
