looking for a job after July

My name is David, I am an American currently living in Guangzhou teaching English. My contract with my current company ends in July and I would like to find a job in Shenzhen afterwards. I am a recent graduate with a Bachelor's in Economics: International trade. I minored in Asian studies and Mandarin Chinese. I speak Chinese at probably an intermediate level and I can speak basic Japanese. If anyone can direct me to some places to look for job or internship opportunities I would really appreciate it.
