I need a business writer to take content with an old document, and make it new

I have a 1000 word document in which I would like the content to be refreshed/revamped. I would like the fundamental message to stay the same, but it needs to read and sound original. The document talks about how to design contests/challenges in the best way for crowdsourcing platforms. I would like this done in a few days from when the project is awarded
