translate english to spanish

I need a professional translator to translate an English text into Spanish by the deadline of 4-7 days. The language to be translated is English to Spanish. I am looking for someone with extensive knowledge and experience in translation, who is able to produce an accurate and precise Spanish version of the text. The translator should be familiar with the proper grammatical rules and spelling conventions of both languages. The translator should be certified, but this is not mandatory. If you think you can do the job, please reply with your rate per word to discuss further.
NOTE: I WILL ALSO PROVIDE YOU WITH THE SAMPLES. ONCE CHECK THE ATTACHED FILE.
