The question is about how attract and what to offer to people who you want to be behind your start-up? It's easier with developers and other positions where you can translate their hours to pay at a defined rate, with industry experts it's probably different.
For example, there's a guy who I want to approach and he's an expert in affiliate marketing and merchant data feeds, but I have no idea what I can offer in a start-up that has nothing except web site in development and some interest from investors that might not immediately translate into funding.
