On the one hand what you're saying seems somewhat fair, but on the other hand, I prefer encouraging the attempt. A portion of the people who do this will never have to call you, having managed to solve the issue, and any experience gained with the attempt will go into doing it better next time.

In a world where people know less and less about how to solve problems themselves, I think repair skills are incredibly important for people to have.

Personally, I would happily pay more if you show me what you're doing and/or explain what I did wrong :)

Yeah, I had the pump on my washing machine go out. I called the repair guy, he said there was nothing to fix, it just needed a new pump. He told me he could do it for $X (on top of the call-out fee), but it wasn't that hard and I could find the replacement pump online for ~1/3X and do it myself. I did that and it took 20 minutes. We will definitely be using that repair company in the future for anything that isn't immediately obviously trivial
