Hello!
I am fluent in English, and have a solid experience in writing and translation, as well as editing/proofreading. You can see my test score here on Freelancer.com (top 5% of takers), and I can provide you with my TOEFL score sheet (perfect score in Writing - 30/30) if needed. Let me show you my skills, and you will not regret it!
Best regards,
Nikola Markovic
edit: in the meantime, I have passed the Freelancer.com US English Level 2 test as well, with a score of 98% (top 5% of takers)
