While I have a full time job I like, I also like IT architecture, such as building out a buisness and its resources confined to a budget and all, how many people do stuff on the side like consulting or helping small businesses fix or improve infrastructure? Is it hard to do? Would a buisness license be required?

I realize it'll mostly be networking but it's a thought I've had in the back of my mind. Seems like it would be a fun side job, maybe not an ongoing thing as if I was a solo msp but more of a lets give you a list of things to improve and a plan to do it type thing even help set stuff up maybe (which i woupd probably enjoy too but might take way too much time).
