I am a native mandarin speaker, lived in China for 20yrs. I have well enough English skill also.
I am experienced in graphic design(websites mostly), and I designed more than 20 posted flyers and posters online and offline.
I raised budget and time because I will submit 2 samples for you to choose. (usually, it saves time for both of us) In addition, design a series of flyers take time.

To help you design a flyer suitable for Chinese market, I will also make a collection for you for reference.
