Client satisfaction is the main factor
In Indonesia it is very difficult to find work unless you come from a rich family. I had several businesses related to hobbies but failed. This is because competitors produce too many goods and do not think about the small size of the market. And consumers here will sell more of the goods they buy at the cheapest prices possible because they need money quickly (in some cases because of online gambling debts)

open when I have free time (please ask first), the price you have to pay will not drain your wallet
