The higher you charge, the more horrible your consultancy job will be generally ;-) I've found €200 to be the sweet spot between actually doing useful tech work and being in nonsense meetings all day.
All kinds really. From transitioning companies to modern CI/CD practices to security counseling to integration work to helping out with automation and such. It's about 50% low level tech stuff and %50 advisements.
I think I should stress the point that people will pay more for stupid things such as lessons than they will for actually useful things. For example, you can charge twice as much for teaching people how to use Git than you can for actually implementing the frontend and backend for them.
People are really, really insecure about their own abilities. If you can position yourself in the market as someone who can help them with their insecurities, you're basically golden. It sounds a little .. dickish, but really ,you're doing everyone a favor. So many people get hung up in merely(?) having to make a decision. Making it for them it usually a big help.
That's very helpful (if a bit counter-intuitive), thank you! Isn't it kind of contradictory that, on one hand, you teach people to make decisions for themselves, and on the other you make them for them?
Common mistake -- you might want to look into Patrick McKenzie's material about consulting. Some clients you'll even be able to say "I'm raising rates" and just start getting more money for the same work without issue.
I doubt it's going to be that easy, because some clients already balk at the current rates. It greatly depends on your niche, that's why I asked the GP what he was consulting on.
Clients always balk at rates. Fire the worst ones and keep the ones who pay up if you can. You should always be looking for better clients (i.e., doing outbound sales) if you want to charge more.
