Hi! I am the person you need to carry out the job. My deep knowledge of both English and Spanish guarantee an accurate, 100% human translation. I am a native Spanish speaker with equally advanced grasp of English. My pronunciation and fluency in English are almost nativelike.
If you wish, I can send you a text/video clip/voice recording showing you my skills. This might help you decide whether to choose me or not.
Thanks for reviewing my proposal.
