Taking on a project that has never been done before can be very risky for any freelancer. You might spend a lot of time working on an idea that ends up failing because the client did not plan it well enough. I usually look at the budget and the timeline to see if the person is serious about the experiment. It is also important to know if they have a clear goal for what they want to achieve. How do you decide if an unproven project is actually worth your time?
