Chongqing to Yibin by bus or ferry

We'll be arriving from Beijing by train in the morning of the 6th of August. From there, we will be following this itinerary:
Chongqing - Yibin

Can you please give some information on bus/ ferry schedules from Chongqing to Yibin? How much do they cost and how long is the travel time? Info on bus timetables, cost, and travel time for Shunan Zhuhai and Panzhihua to Lijiang would also be appreciated. Thanks in advance!
