This pays for at most a week of work. I doubt it is worth anyones time to do unless they would do it for free anyway. Between the risk that someone else does it first and gets the reward and that if you are trying to make a living you need to spend time finding the next thing it just isn't much.

if you can fund someone for at least 6 months of work it becomes reasonable to work for these.

Edit: Looks like many people are not understanding how overhead works. Your take home pay over a year is just over $100,000 since you end up so much unpaid time looking for the next gig.
