As every paper is different I do not have a fixed price per word. Some papers require extensive editing, while others very little.
The way I price is when I receive your paper I proof perhaps 20% of it, and return it to you as a (free) sample of the quality of my work. At that point I will give you a fixed price to complete the paper.
To give you an idea, most academic papers have cost my clients Kr1200-Kr3000 depending on their length and the quality of the original.
Remember, it costs you nothing to try me!
