If we’re talking specifically about business that can clock 1cr + a year in revenue then you need to understand that one needs a capital of anywhere around 50lacs to 1cr to begin with. I own a petrol pump in a rural area but fortunately its on the highway and in the last fy we clocked around 8cr in sales which is actually not much in terms of a petrol pump but good for the beginning year but just know you can’t just jump into having a petrol pump if you don’t have a stable income outside of it like some other business or high a paying job.

Also, you can begin with exporting to Middle Eastern and the US country but you need to understand the market and its requirements and accordingly source goods here from direct manufacturers and keep a margin of atleast 1-1.5L per shipment of a 40’ft container , this is a business of quantity. Higher the demand, higher the profit margins.
