Hi there,
I'm an award-winning copywriter with around 5 years' experience in the advertising industry.
From your job description I gather that you require someone with editing and proofreading skills to review your website copy. I can do this, as well as identify keyword phrases and incorporate them into the copy for SEO purposes. I will also make appropriate changes to the copy to ensure it reads well.
For this job I would offer three rounds of changes so that you are happy with the end result.
