Translation Job

I need someone to translate a document that has from 6,000 to 6,500 words from Spanish to English. I prefer an experienced translator, not someone who translates word by word (like Systran) but someone who has an understanding of the mechanicals of the English and Spanish Languages. there are expressions that change with the translations and you have be able to detect that and translate the idea as well. An ideal candidate would be someone who grew up speaking English and Spanish and has excellent grammar skills. The translations will be about marketing health products with descriptions. You can send me as sample of your work half a page of some previous translation from Spanish to English you have done for someone in the past. I pay per word so please send your offer.
