Ask HN: How to start a software consulting company

I work as a software engineer and I recently finished my Ph.D. in Computer Science. Programming is not just my job, it has been my hobby for as long as I remember.

I always wanted to have my own software consulting company on the side where I could help other people solve their website or cloud (Azure or PaaS) problems. That has always been my dream. I am not sure where to start or how to approach people or which meet-ups I should attend. Especially after finishing my Ph.D., I have a lot more free time and I don't like to waste time, instead, I could help other people.

I appreciate any guidance or feedback. Thank you
