Tourist L Visa application upon arrival at Tianjin Cruise port

We are a group o 6 adults and 4 children finishing a cruise in Tianjin then travelling into Beijing for 2 night stay then fly out into Hong Kong stay 3-4 nights before going back to Perth. Can we apply for a tourist L type if we book a tour picking us up from cruise terminal on our way to our Beijing Hotel. If so how much would it cost.
Thankyou Luci
