good post, re spending $1k to test out the hypothesis....the challenge for me as a first time entrepreneur has been exactly where to place that first (or only) $1k. do i get some mockup work done to show potential partners/investors how it will look? ...build some foundations of the initial code (paying someone to do that)? agreed to invest a little and test the idea, i think the challenge for me is what is the most productive first step in doing so.
