Chinese Marketing Material Proofreading

I need a fluent/native Chinese speaker to read and proofread a business document written in Chinese. The document is for marketing purposes.

Review the content for:
- Grammar and spelling
- Sentence structure and clarity
- Tone and professionalism

The goal is to ensure the text is natural, accurate, and professionally written. Ideal candidates should have:
- Native proficiency in Chinese
- Strong background in professional Chinese writing
- Experience with marketing materials
