Native Spanish Translator / Proofreader needed for an e-commerce project

Hello,

I need someone who can translate my website ( https://goo.gl/q2mdTH + transactional emails ) from English to Spanish - a native person would be ideal. We translated previously our website to French, German and Dutch and it took between 17 to 20 hours each. Luckily, we started the translation from english to spanish, so the first part of the job is to proofread and correct what has been translated already and then finish the translation of the website - so we're looking at around 9 - 11 hours total.

You'll have to work from a google doc spreadsheet, we're not looking for an exact literal translation, more something that feels genuine and reads really nicely in the translated language. Deadline is around end August. You'll have to agree to an NDA. Many Thanks !
