Other people will not put cash on the table if you don't. I think it's unrealistic for a business start with one person only putting in sweat equity and others putting in all the money. You've got to put some cash on the table because that shows your faith. I do understand your rationale about putting your time in. It gets complicated with the legal ramifications, but it is the only way for you to get the idea to the marketplace without doing it yourself.
Ideas are a dime a dozen.
