Native German proofreader

The task will be to proofread the documents containing all the texts from the online dating site. We are sure that a lot of text is incorrect so we'll expect you to make some changes.
It will contain HTML code, you don't have to do anything with that, leave it the way it is, not to delete it from the document.
We consider native German speakers only.
There will be a very brief test task to check your expertise and German level.
The price is negotiable.
