Translation of short e-book from English to Spanish

I need a short e-book translated from English to Spanish (Spanish from Spain). The book is on a very general topic, so you won't find any specific technical jargon in the document. I'm a native Spanish speaker, and I'll proof read it after delivery, so I require excellent translation skills. I would provide the original in word format. The total word count is approximately 6000 words. Please, provide some samples of translations you have done when you bid.
