Recent research into online peer feedback shows that people who give feedback to others on what that person has written benefits the person giving the feedback more than the person receiving it. This isn't typically what people expect: they will pay for feedback on their writing and then revise it. That will solve the immediate problem with that specific piece of writing, and if that solves your current problem, great!
To improve as a writer in the long term, however, you need to go beyond receiving feedback. You need to learn to "read as a writer": find texts similar to the one you are trying to create, and then analyze them to find out how they are put together. If you then try to explain (to yourself, if you do not know the author of the text you are analyzing) to the person who wrote the text how you see the text working (or not working!), then you've taken the next step.
Over time, you ability to see opportunities for revising your own work will improve. It helps if there is some standard or criteria for your text. We can help do an initial analysis to identify the features of your target texts, and we can also help you improve your ability to comment on other writer's texts in ways that are productive for you and them.
