website editing

I need a fast, accurate copywriter to edit/upgrade a one page website. The page is longer than usual, however there are many technical terms, testimonials and repetitions that do not require much or any editing. The quality of the existing copy is very reasonable (see a part of the copy attached). There will be a certain bonus if you can improve the copy in any meaningful way to make it stronger from a marketing perspective. I expect to pay around $50 not including the above-mentioned bonus. There will be more similar work right after the completion of this project. Previous experience it editing/copywriting website related marketing pages would be considered an advantage. Please point out to where I can see some of your work.
