Traducción del español al inglés de power points de psicología

I am looking for a translator who can assist me with translating Spanish to English Powerpoint presentations related to psychology. The content of the Powerpoint presentations is between 500 to 1000 words (each power point) and there are certain terminology and concepts that must be given special attention in the translation process (just a few). Furthermore, there is no preference for the use of US or UK English.
