You'd be better off looking for general business advice rather than a "start-up". The "start-ups" à la YC looks to raise money, several rounds, IPO, Exit, spend millions to acquire users, etc...

It's much different than building a small business that scales to 10 employees in the next 10 years.

The difference also starts from the foundation. For startups you are looking for Corp C. For your case you are looking for an LLC.
