How do I get a work permit while already in China on a student Visa?

I am a student in China, with two months left to graduate. I already have a BSc from several years back and related work experience.

I need to know how I should go about applying for a work permit, so that I can get it done without leaving the country, and before my student Visa expires. This is of course with the assumption that I have found a job.

What do I need from the school in order to begin the process? I’m a non-native speaker, and schools don’t help non-native speakers with the process.
