Ventures including but not limited to business acquisitions, real estate investing, building & funding startups.
Your question is very open ended. You're starting with the business structure instead of a money making idea.
The part that concerns me is that you want to issue dividends to all the shareholders for businesses that they 'do' together.
Doing usually entails working for wages/salaries. Dividends are the returns for putting capital at risk.
Arrange a call if you'd like to talk and sort out your ideas a little more clearly, I can help give you some direction.
