Translate 320-Page Storybook to Spanish

I have a 320-page English storybook that I need rendered into polished, formal Spanish for an adult audience. Cultural references and idiomatic turns of phrase should stay exactly as they appear in the original; no localisation is necessary beyond faithful grammatical adaptation. Faithful meaning does not have to feel stiff, though—narrative flow and literary flair still matter. If you rely on CAT tools such as Trados, memoQ or Wordfast for terminology consistency, that is welcome, yet every sentence must read as if it were written natively in Spanish. Deliverables • Complete Spanish manuscript in DOCX (chapter structure, headings and pagination preserved). • Companion PDF showing the final layout for quick review. I would like to review the first 20 pages within one week to confirm tone, then agree on a realistic schedule for the remainder. When you reply, please tell me about any long-form fiction you have translated before and the timeframe you propose for finishing the job.
