Startup Company Structure

Assume I have a genius idea for a startup. Something like Netflix if Netflix doesn't exist.

I am working with one other person. I'll be the founder and he will be the first employee.

Also assume that I will have a decent demo and very compelling pitch for investors in 6-12 months, at which point either we raise decent money and quit our jobs, or we potentially drop the idea for now. Until then, maybe we hire another 1 or 2 early employees, but probably not.

I eventually see this as a multi-billion dollar company where I intend to have a dual class structure where I always have super voting shares.

If you accept for a moment that the idea is indeed genius, and that I will be able to convince investors to fund us while allowing me to have super voting shares. What should I do as far as

1) LLC for now and later change to C Corp, or directly C Corp from now?

2) Do I need to set up the dual share structure from now or can it be later?

3) Do I do it directly in Delaware, or start in California (where I live) and then move it to Delaware later?

4) Is it possible I can set it all up myself using LegalZoom or should I definitely use a corporate lawyer?

Any advice is appreciated, thanks!
