Dear, Mr. Tomislav Jelic,
Let me introduce myself, my name is Akil. I am a native speaker of Indonesian language. Currently, I live in Indonesia and just doing freelance job.
First of all, I need to know further the details about this project. I would like to know what the topic is about since I have not found the test file you mentioned above here so that I couldn't predict how much time I need to do this project. However, for your information, I did proofreading my technical documentations before. There are 30+ technical documentations that I need to do proofreading. Each file has 15.000-50.000 words. I can do proofreading 1-1,5 files daily (weekdays), even 2 files daily in 5-6 hours. So, it's about 10.000 words in 2 hours. For first bid, I will propose the maximum fee to do this project in 3 months calendar (in case 2 hours daily and in 5 weekdays = 200.000 words in a month). However, I need to discuss further with you regarding this matters to readjust.
I am new on this platform, indeed. But I have some experiences about proofreading, including translating an official book (owned by United Nations) from English to Indonesian language twice, including made some presentation matters about them. Feel free to contact me if you are interested. That's all and thanks for your attention.
Best Regards
M. Sidratul Muntaha (Akil)
