@thibaultamartin I self host too and I also host other people. However, I don't do as much of it as I used to. Hosting other people is a huge headache so I let that business fade out.
I never made a serious effort to grow my #hosting service. It ran it as a social enterprise.
I didn't just offer good hosting to them, I also offered them support and advice they could trust. That kind of service is something that I should have valued more and priced in a way that was more fair to me.
Offering artisanal hosting run by an expert who knows you, your site, and your goals is something I wish I had more time to do. I'd love to see other people build a business from this model. My advice is to be sure to price it fairly to yourself and clearly explain the value you are providing.
