Teaching English and only 22

I want to teach English after I graduate next year and I will be 22. I will have a bachelors degree. I also have an accredited 150 hour TEFL and TESOL certification. However, I read somewhere that you have to have 2 years (post graduate) work experience to qualify. I will also be volunteering to teach English this year and my senior year, will this qualify me?

I've been dreaming of going to China, but even though I will have these credentials, will it still be impossible for me to go until I'm 24 and have two years experience AFTER I graduate?? That is way too long!!
