Photography apprentices have free time and high income.

300, are you kidding? Too few. Now the monthly salary of apprentices is also several thousand. I suggest you choose someone who can earn money and learn technology. Look at you, you are a little old. Three hundred really doesn't suit you. I am from the countryside, too. If you learn technology first, you can earn more with it. Even if you start your career in a year, do you have the capital to invest in a photography shop? There are slackers who do well and those who don't.
