Don't worry I am the best.
I will provide samples of my work if you message me. You're requesting a 25-page story, single spaced I'm sure, so that's close to 20,000 words, or about 20 hours for a fast writer. I cannot imagine a quality writer producing 20,000 words of original, quality content for $100. They'd be working for less that $5 per hour.
If you want top quality, message me.
I just completed a 50,000-word and a 40,000-word novella for separate clients here on Freelancer in the same style that you have described. I charge $125 per 10,000 words and write 100% original content with perfect, polished English. My university background is Honors English and Russian Literature.
I have been published by over 60 magazines and newspapers, including by the Smithsonian Institution. I have published dozens of stories in New York magazines and nine novels with American publishers. I have been a journalist and editor with many hundreds of published articles. I have published well over a million words. I work quickly and efficiently.
