I'd need someone that has extraordinary skills with manipulating presentations. You get some text from us and you make a professional looking and smooth-going presentation.
Our presentation will consist of ~15 slides and we've prepared the describing text for it. You'll have to go through, find what fits where, place etc.
We will also be using some kind of "calculator" that has to be "programmed" in the presentation, where we plan to fill in numbers on every next slide and at the end it manipulates a chart to show values change and stuff.
So, your English needs to be perfect and you need to be creative!
