I know how much times it takes to do a good translation of 1k words, and given the living cost in DK, 15$ is just a complete waste of your time, hence the suspicion.
Because working from your PC is extremely flexible, I actually started the gig out on 10$ per 1k words. I am well versed in the English language and consider myself a pretty fast typer.
Unfortunately, at 10$ other Fiverr translators (actually, a whole syndicate of them i think) used my gig to fulfill their own orders. It was fine for a while but when they suddenly came with 8-10k word documents I had to say enough is enough for the reasons you mention.
Thank you for suggesting a review of a fellow Dane, how does he prove he is also native Dane though?
I did consider translating your first post in Google translate, and post it besides a native translation and then hopefully some random Danes come by and verify that the differences are key. Though, seems inefficient
