I understand that most people here are tech savvy.

I'm an power user when it comes to computers in general, including Bitcoins. Recently I wanted to offer a computer help to people who might have difficulty doing something on their computers and smartphones. People would pay me in Bitcoins if I manage to fix something. Of course it's going to be escrowed so the people can't try to scam me.

I'm aware of TeamViewer screen sharing, however, the risk is that people might call me a scammer because it allows me to control the computer which I'm connected to, even though I have no malicious intentions. So what app should I use instead?

How high should prices be?
