Thank you for your quick responses. However, that's the problem for me that I am lack of connections with CEO/COOs. But I am pretty interested in what you mentioned that there are several great law firms which provide incorporations service for free. Could you list some of them for our reference. I think more people may benefit from such a information. Thank you.

You don't need connections to reach out to startup CEOs. They are visible and you can easily find or guess their email addresses.
