Got any advice for a novice guitar instructor?

Other than don't do it lol.
I've got people bugging me to give them guitar lessons. I've never done that, but could use a few extra bucks. Mainly never done it because I'm a lefty so I figured it wouldn't work right. But people say it would be good, like looking in a mirror for them. Plus, I've never taken a guitar lesson. So I haven't been through that routine. Though I did have plenty of lessons on brass as a kid when I played in school band and orchestra. So I know that drill. I know music and can read and all that, but so much of what I do with a guitar is intuitive and unexamined.
But, they're bugging me, extra money would be good, and I've got no problem sharing what I know. So I guess I'm gonna do it. These would be people who've played a bit, not beginners. I'm thinking of sitting down with anyone for a half hour for free and seeing what they're looking for and if I can do something for them, then charging from thereon if I am of use to them. Any tips????
