If you are talking about buying a paper instead of writing it, I think you are wasting your money. Maybe you have trouble writing in English, but actually you can write a list of sentences here in this forum and we will help you turn it into an essay. That is the way to become a good writer.
I want to show you this example of someone who speaks English as a SECOND LANGUAGE and has become very skillful by practicing here: http://www.essayforum.com/essay-writing-feedback-3/schools-should-ask- students-evaluate-teachers-16684/
Even if you just write some sentences, we can help you to make them good ones, and we can use them as the topic sentences for paragraphs in your essay.
Try writing a paragraph:
Write a sentence about something.
Write a sentence with an example of what you mean.
Write another sentence to explain some more.
Write a thoughtful conclusion sentence for the paragraph.
I also hope you will help other people here by looking at other people's essays and telling them what you think about the them.
I wish I was bilingual, like you! I hope we can help you improve your writing!
