Am I correct in assuming that if I wrote all 5 section I would receive.4 btc?
That's not the idea I got from it, considering the title of the thread states "paying 0.08 btc"; I think that's for the whole package.
Now imagining all that requires only 1000 words (unlikely), that would be 0.00008 btc or about $0.05 per word, at current prices. That's not a very generous offer for what you're asking.
I get the feeling people would find better deals than this in sites like odesk, freelancer or the like.
