Hello,
I am interested in your project. I am a Vietnamese native speaker and good at English writing and speaking. I have a Sony F8322, Android 8.0.0. I have done some small projects related to mobile website translation with some clients on this website (please see my reviews in this page). Actually, I haven't worked as a content editor but I believe I can do your work well with my best efforts. In addition, I can join your project 2-4 hours/day if you want.
Hope to work with you.
Cheers,
Van
