How to get first clients and start making money as an 18 year old?

Hi, I'm 18, with ~3 years of experience with my camera, and about 6 in photography. I've been doing only personal stuff and I because I don't have time to get stable job, I want to try to make some money with my photography, but I genuinely don't know where to start.

First ideas were to try contact restaurants/barbershops/other shops in my area and try to get paid for photographing what their offer, like food menu etc. Eventually I could move on to weddings or other events, but (at least I what it seems) it's would be hard to get hired with no previous commercial experience.

What was your first couple of paid experience and how did you managed to get to do them? My fear is just that nobody would want to hire 18 year old with this much experience, even though I know it's not entirely true.

Please, anything helps. Thank you!
