How should a young band find more commercial performance opportunities?

In the early days, the band can increase their income by doing some instrument training. For example, guitar training, drum training, and electronic keyboard and piano training, etc. You can enter training through the band to increase your income as quickly as possible. You can do this by going to commercial gigs, that is, taking orders. For example, going to bars to do some residency, taking orders for some openings or annual meetings and carnivals, etc. If the per capita annual income is better, 100,000 is not a problem.
