Personally, I think it's a reasonable amount given that you have to pay taxes on it, you have to get health insurance for the 3 months that you are working on it (not cheap), and the position is not extendible after 3 months. In other words, you have to consider this as a 3 month contract as an independent contractor with no chance of extension. Personally, that would be pretty far into my discounted rate ;-) Still, if successful, it has the upside of giving the author chances at a good reputation and follow on contracts. I'm very interested to see how successful this is. I'm sceptical that it can be completed in 3 months, but wish the author the very best of luck!
