What help do you need now?

In the process of creating a startup, I faced many problems: 1) How to evaluate an idea? 2) How to find competitors? 3) How to prepare legal documents? 4) How to find an investor? 5) How to find a co-founder? 6) Etc. I know that I'm not the only one who faces similar problems. And I decided to create a site where, with the help of specialists, I will try to figure out how to solve such problems. Please write what problems bother you?
