Have the person put the money in escrow is all I can say, but I will be honest with you, the people on Freelancer (was Get a Freelancer) will give you work, without knowing you. However if you copy information at all, or if you write without perfect English, you will not get paid, because while Freelancer watches out for writers they also watch the quality of your product to make sure that the people buying your product are not taken advantage of, I am only saying this because it looks like (from the way your write) that English is not your first language, and if it is then you will need to clean it up for your project to be a success.
