 Am I crazy?
anamax: You need to be able to convince your interviewees to participate.  What's in it for them?  See http://scobleizer.com/ for someone else who has solved that problem.One problem is timing.  It's not sufficient to turn the interviews into enough money, you have to make that happen at the right time.I think that your budget is a bit low, but that doesn't mean that this will be more doable later or that it's not doable now.
