I need to take a bus to Beijing from ningbo

I have a big problem. I am American living in NB city, china for a while and am in the middle of getting my visa extended. The government has my passport to do the visa process. I need to go Beijing as an emergency and since I do not have my passport in my possession at the moment I cannot take the high speed train. I have no choice but to take the bus to Beijing. I would like to know how long it would take to get to Beijing in a bus, the price, and the time schedule. If someone can help me with this, I would really appreciate it
