Native Swedish Proofreader

I am looking for a native Swedish proofreader to correct a set of short articles in Swedish. There are 25 articles in total, of about 400 words each, with very few technical terms. What we are mainly concerned with is the language style, as well as the usual grammar and spelling, so you must be a native speaker to be considered for this job. An example of what the articles look like can be found below.

If you accept this job it will be of a very fast turnaround time (24 hours), so please make sure this will be possible before you bid.
