Copy Writer - Great English Grammar To Go Over a Live Landing Page

I am seeking a Proofreader who can review a live landing page on Go Highlevel and double-check for grammar and spelling mistakes. The page is 1000 words long approx and the job needs to be done in the next few hours; excellent English grammar is essential. The job will also include recommending changes based on reviewing the site on how we can improve the landing page. Must be able to do it immediately.
