I know nothing about businessy things. Shares are evil to me - a fake product that doesn't exist in my mind.
However the issue is how many shares 'we'd' need to control it, how much they are (incl brokering), how to set up a shareholding and possibly a website that enables members to vote on issues so the executor/ceo is acting in the will of the shareholders. Figure out a way to get a CEO. Then kickstart for that much. Then hope.
