Me too

I wouldnt call this “easy”, anyone can make money doing almost anything if you do the work. This would be promoting an event, renting space, insurance liability, backups if a performer or performance part falls through. Its still risk and work. But you should try it! Im in a big city and these events exist and are marketed as candle light concerts, where they do just what you said and just have like 2,000 candles everywhere. So its profitable if done right!
