This is the kind of stuff I sit and do anyway. haha =)
I did a Masters in Science Communication i.e. how to communicate science to the public in the most simplified, basic way. How to popularize it. The weird thing is i might actually enjoy doing this. All the best anyway.
Oh also i just joined freelancer.com yesterday, so i'm afraid you have no references to go by. There's a first time for everything.
Cheers
