Hello, I think, since you ask this question, you should have been exposed to tuning or have some skills. This business is very promising. Andhadhun, audio rental units, dance halls, bars, equipment schools and so on all have demand, but the requirements are also very high. You must have good skills, and before you can become the ace Andhadhun, you have to do other jobs more or less. For example, the audio rental company will let you sell. Our school organizes parties, and Andhadhun's commission is 500+, but parties are not held every day, and the technical requirements are particularly high. Moreover, the bar staff is highly mobile, and there will be demand in this respect. As for schools, academic qualifications are often required.
If you have good skills, you can find a part-time job. If not, please start as an apprentice. Andhadhun used to work part-time in colleges and universities. Of course, I studied by myself for a year. Before you do it, you should conduct market research. It's best to visit several bars, audio rental units and universities, ask about the demand, and then plan according to the actual situation.
