You're already in one of the best communities there is: Hacker News. Don't underestimate what you can learn just by carefully reading the threads here.

I went from "idea in my dorm room" to interviewing and hiring executives in their 40s and 50s within 24 months. The best lesson I learned is that there are way fewer "rules" than you think, and smart, disciplined, focused entrepreneurs can accomplish way more than they assume. It's reasonable to reflect on your inexperience in order to prevent mistakes, but you should never feel intimidated by it, or let other people intimidate you. The world (and YC's portfolio) is full of "inexperienced" people like you who have built billion dollar companies that disrupted industries and became pillars of the economy.

If you post contact information in your profile, I'm sure at least a few people with relevant experience would reach out and offer to be a resource for more specific advice. I've done that a few times here with mostly successful results.
