I have done this recently, through upwork for a tech related topic. I am very comfortable with platform but I'm sure I could have used a different one for other topics.

Posted a job description – initially setup by asking gpt4 to help write it down, then grammarly to make it solid; setup interviews with a bunch of people; got on a call with a handful; chose one whit whom I'm working with once or twice a week.

Did it because YT tutorials were not helping, because there are a lot of them(hot topic), from many different people, with quickly outdated material, and un-interesting or annoying people(too many memes, jokes, or segways).

Now I have someone I pay to get on a call a few times per week, we go over the assignments, I ask questions, they tell me what to look out for and how to do it better.

I have accepted to pay per hour a bit above what I make on my fulltime job.
