Even who are the native English writer do many mistakes which they think are not counted in mistakes. Actually I have written content for websites from a long time and have much experience inn this field. You can check an example of my writing here: https://mytechmarvel.com/how-many-jobs-are-available-in-consumer-services-field/. The services provided in the topic are looking fine. In my graduation I have taken advantages of such services. SO at the end I want to say to the new writer that practice makes the writer perfect, and that's all.
