I posted on Craig's List looking for help developing an idea into a web app. Since there's no money/funding/compensation the thinking is we would take a percentage of the company and the income it makes when profitable (down the road). One developer suggested 60/40 and another 50/50. I thought both proposals were relatively high. Granted the potential developer would take on most of the coding, but that's basically it. I would handle everything else (business end stuff - marketing, advertising, operations, administrative, planning, etc.). Plus I'm a very capable developer and designer myself.
Am I wrong in thinking 60/40, or even 70/30 is an unfair split? Am I unrealistic because its my idea? If so, what is a fair and balanced share schedule in this situation?
