Translation job

I am looking for a translator for a project that requires translation from English into Spanish. The project requires quite a bit of text to be translated, therefore accuracy is of utmost importance. I do not require the content to be proofread by a native speaker, however clarity and fluidity in the translated material is highly desired. The translator should have an excellent command over both English and Spanish, in order to ensure accuracy in the translated text. It is important that the translator have a deep understanding for both cultures, in order to properly convey the intended message. I am open to creativity and different interpretations of the material; as long as the accuracy and integrity of the content remain the same.
