Curious to hear from estheticians and others about joining the industry

I’m considering becoming an esthetician because of my interest in skincare and the career in general.

I have been getting electrolysis done for about the two years now. I also just started getting laser removal as well. My last appointment, my technician was telling me about how they also teach people how to use laser (sorry for the lack of technical term here) and we got to discussing her experience as an esthetician. It made me interesting in the job. In particular, I would be interested in learning how to laser hair removal or electrolysis or becoming an esthetician as well to do facials. I would be interested in doing this full time for maybe two or three years and then doing it part time as a side job. Does this make for a good side hustle job? I think I would enjoy doing it a couple nights a week. I have a lot of questions about the logistics of that though. I have done a little research but it’s hard to get a real feel for the industry.

I know to become an esthetician you have to train on waxing and other services. Beyond that, is it possible to specialize in only a couple things? Does that really set you back? I wouldn’t really have any interest in waxing but I’m not opposed to doing it.

Do medispa hire part timers? In general it looks like all the medi-spas in my area are 9-5 operations. Beyond my area, is there demand for workers in different times from 9-5? I’ve thought about looking at resorts too. Does anyone have experience with that?

I hear that marketing yourself is so so important to the job. Would the time I put into that justify only working part-time? I wouldn’t want to have to spend as much time marketing as I would actually performing the job.

What is the job market like in general? Is it difficult to find studio space or a job?

Interested what pay is usually like? Hourly or strictly by booking? I know this would vastly range depending who you are working for, but just curious to hear about it.

What else should I consider? I am cross-posting this in a couple different community to hopefully get a wide range of responses! I, of course, have a lot of other research to do myself!
