Translation of articles - English to Turkish - English learning / teaching

The project is about translating content written in English to Turkish. The content is about english (language) learning/teaching. The articles are written in everyday English (not very scientific/academic). I am looking for someone who has excellent English and Turkish skills. The output has to be professional, free of errors, gramatically correct, meaningful. Accuracy is much more important than speed. Enough time will be given, planned time is between 10-20 days. The content is 20 pages long and contains about 10000 words. It will about 15-25 articles combined in a document. While offering a price, please be reasonable as I do not want to spend an unreasonable amount of money. Consider that there is more work to be offered once the job is succesfully completed (long term view). The payment can be done based on 2 or 3 milestones. Initial milestone payment is not preferred without seeing any translation to evaluate. Your work, i.e. translation will be checked by native Turkish person and if quality is low or has many errors, I consider it to be a right to pay less than the initial agreed total price. So please do not bid if you are not qualified. Please write I AM THE ONE at the beginning of your message, so that I know you have read all what is written. By bidding on this project you agree to transfer all content rights to me. Content cannot be reused or resealed to anyone. You can bid on my open couple of translation projects. If you can make a discount on the total offer (all jobs), you get more chance to win all! Looking forward to working with you!
