Where to find native speakers to correct my written Japanese?

There used to be a feature on italki.com where users could post something they've written and then native speakers would correct it. Students of Japanese, for example, would write a short story of a description of what they did for the day, and native Japanese speakers would make corrections.

I spent a fair time using the feature, both to have my Japanese corrected, but also to correct the writings of non-native English language students.

Unfortunately, the feature seems to have been removed several years ago. Is there anything else like this available?

I've been continuing with my Japanese studies, but need to work more on output.
