This is Carol from Hong Kong. I am a native Cantonese speaker who can write and speak Chinese and English. Not sure your main Chinese customer is "Traditional Chinese or Simplified Chinese", but I am handle both. :)
I have 9 years digital marketing experience, included hand on experience on Facebook. I am also good at making the graphic. So I can create photo images to attract better engagement rate in Facebook.
To go ahead for this project, I will need to study your website and the branding that you'd like to follow. It will affect what kind of posts that I will create for you, ie: interesting posts with casual tone or formal posts to attract enterprise market.
