Translating of articles from English to Madarin and vice versa

I am looking for a translator to translate articles from English to Mandarin and vice versa. My project scope includes more than 10 articles and I'm looking for a basic level of translation quality for general understanding. Therefore, I need someone who is proficient in both languages and has the necessary experience with translating articles in the chosen language. The translator should also be able to deliver the project on a timely manner. Lastly, I would like to remind the translator to maintain accuracy throughout the process and take note of the cultural differences between both languages.
