I found a chinese company willing to help me with the Z visa

Currently, I am a student in China, but I found a company willing to help me to acquire the z type. The problem is that I graduated in 2014 and they told me that it may be a problem since I need to have 2 years of experience after done with college. However, since I was 18 years old I own a work shop. Right now I am 25 years old, so I would like to know if this would be ok as a working experience.
