Hi,
I have looked at your project, and the need to have 400 articles rewritten for you. This project reminds me of a project which I undertook for a client, as I was given the project of rewriting some articles for him, and ensured that the key context of the article was not changed at all.
I have also written articles pertaining to tourism, and as a native English speaker, and also one who has rewritten articles in the past, I have the competence to complete this task, and can share samples of the projects which I have worked on in the past.
I look forward to hearing from you to discuss more.
Thanks,
