My Business Plan: Book Reports Online

I have one business idea about book reports. The plan involves setting up a company where people can get paid for writing book reports on current as well as old books. It’d be rather like Textbroker only for literature. I’m not sure if I should let anybody write up reports on any book, multiple times or one book report per book. On Textbroker, you get multiple chances to write one original article on a particular topic or person. Then when you click accept you have to write the article under a deadline. I wonder if this idea will work at all but it is designed for people who want to write online in order to make money.
