Dear Mr Lozano,
my name is Kiara Abad, I am peruvian and am currently studying linguistics in Germany. I have worked as a translator in English, Spanish, German and French, and I am very well trained in making presentations in any language. I can use traditional tools like PowerPoint but also modern ones like Prezi, which gives presentations a very edgy look. Given my academic approach to language and since I have also worked in a couple different companies, I am well aware of the selling style you're looking for.
I believe that if you go through my profile you will find my experience to be suitable for your project.
Best regards, Kiara
