English to Spanish

I am in need of a proficient translator to complete a project which requires converting text from English to Spanish. The project must be completed within two weeks and must also include editing and proofreading the content in order to ensure accuracy. The translator must have extensive experience in the language conversion and be able to provide high-quality service. All language conversions must be completed accurately and on time in order for the project to be successful. The translator will also be expected to provide suggestions for improvement of the content as needed. Expertise in the subject matter of the text is preferred but not required.
