1 share 1 vote or 1 shareholder 1 vote?
1 share = 1 vote. A total of 5 million shares, and therefore 5 million votes. I don't think I'll be able to afford more than one share. So probably I'll be having one vote.

well, we need to get the money to build it from somewhere

Yes... that is the problem.
good ide 1 share = 100 buks
5 000 000 shars = 500 000 000 buks
Then i definitely would buy 20 shares, and we will have 499 980 shars left
