English/Spanish Language Learning Proofreading

I'm writing a dual-language book. It will consist of 15 short stories. I need someone to go through each story and check them. Specifically, here's what I need:

- The English translation should be as close to the Spanish text as possible, so it's easier to read side by side.
- Checking the story in English and Spanish ensuring there are no mistakes.
- Reading the sentences and making sure that there's no repeated vocabulary. If there is, rewrite the sentence.
- Making sure that the quiz section (in Spanish) has no errors. Each answer is listed as A, B, or C.

Also I need you to keep the format intact, including the tags at the beginning of the content. I need this work done within three days.
