Expert Chinese-English Translation Needed

Several ongoing assignments require clear, faithful translation between Mandarin Chinese and English. The bulk of the work is general in nature, yet it often branches into specialised pieces such as:
• marketing materials
• personal documents
• social media posts
• journalistic copy

For every file I provide, I need the meaning, context, and register carried over seamlessly so the English reads as naturally as the original Chinese (and vice-versa). A neutral tone is essential unless the source text dictates otherwise. Terminology must be consistent, idioms handled with cultural sensitivity, and the final draft free of anything that looks machine-generated.

You will receive editable source files and a brief style guide. Once translated, please return:
1. a clean, publication-ready version, and
2. a tracked-changes file highlighting any queries or terminology decisions.

Deadlines are firm but reasonable; open communication is important, so flag issues early and I will do the same. If you have proven experience in Chinese–English translation, attach one or two short, relevant samples (links or PDFs are fine) so I can see your style. Looking forward to collaborating on precise, natural translations delivered on time.
