To be a bit of a devil's advocate here, even the best teachers have students who injure themselves in their class. A teacher, even the best of the best, can't control the student entirely. (This is why insurance is a good thing, and typically, teaching out of your house incurs a certain amount of liability which your homeowners will not usually cover.) But good teachers definitely have the awareness to nip bad technique in the bud, keep safety first, and bring the right learning attitude to the class. I can't tell you how many times I have seen students push the no pain no gain attitude, but they can't recognize the difference in the pain of effort vs the pain of injury.
It's a sticky situation, to be teaching. To some degree, you protect yourself with getting insurance, setting up an LLC or company, getting a certificate etc. etc. But by the time you have done all of that you are behind money and time-wise. Plus other things can come up, ie, I can't teach out of my apartment, running a business there is a violation of the lease terms. So I would either have to do it under the table, or find a studio. Good studios will require a certain amount of training, likely won't have prime times available to you, and might need you to function as a subcontractor (more paperwork) so they can cover their asses. If someone just lets you walk right in and teach with no effort on their part, they probably aren't running a tight ship. Which isn't a problem usually, until something bad happens. Pretty much none of it is a problem, until something bad happens.
Suddenly, a few lessons on the side for pocket money become you losing money and time. I would agree with some of the other posters, if you just want a little pocket money, it would be really hard to do with teaching pole if you want to jump through all the hoops to do it right and make the time commitment. If it's a passion for you, go for it. If you just want to trade some time for working out pole with a friend for something they have, I wouldn't go crazy. But since you are advertising teaching pole, make sure you are capable of doing so, and doing so safely.
