I am an Early Stage Researcher in a bigger project. I am non-native speaker of English and I find my level of English in my articles not satisfactory, especially when I consider that it is not just my reputation but also the reputation of the project.
I am thinking about hiring a proofreader for my future articles or other texts for publication.
My long term goal is to improve myself enough so I would not need a proofreader in the future. Does the possibility to see your corrected text help you improve your writing skill in the long term, or are English classes necessary?
