Hi,
You can find my academic and professional background in my profile.
For your information, I am a Dutch native, and it's no problem whatsoever to take a test before starting.
Your project description is quite clear, so I'll get straight to my proposal:
Price: 15'000 words per week x €0.02 per word = €300
Time: 6 days maximum
Style: I'll keep you readily informed on progress (I can send you the work in parts if that's your preference) and I'll be available on Whatsapp, Skype, and via email.
Work: Written in native-level Dutch, and the content will be 100% original, based on the existing material that you have.
My goal is to take this work out of your hands, and to deliver it to you as promised on or before the agreed upon deadline.
I hope my profile and bid are of interest to you, and that you'll be willing to give me chance,
Take care,
Max
