I am a native speaker and i can assure you that i'll give you the most natural result.
If you think i'm qualified to help you with your project, hire me and i'll do my very best(since i don't want to mess around here, i'm kinda approved to do the job carefully, right? ;P). I can spend my whole weekend, so i think i can handle 734 words.
Also, i'll use CAT, so don't worry about any errors.
Thank you for taking time to see this.
