The best business model is one with high barriers to entry, high margins, not capital intensive and is easy to understand and predict. Basically a monopoly. That doesn’t mean it’s good for the people or the country. On the contrary, it’s good for the owner.@Thegoodshepherd
A cement plant would be a great money maker considering the development happening nation wide. Plus it serves as various materials for other products globally. The limestone are in PL(high grade too judging by the aging and light colour and why their are foreign people doing inspection on our rocks grade), I'm not sure what makes extracting limestone process so difficult, setting up the mixture formula needed and equipments and storing it in a warehouse(long life product unlike agriculture) and selling it to construction or retail companies by the tonne or kilos, PL truckers will get loads of job to drop of deliveries.
The best business model is something you can store and hold and not sell at a loss due to expiry dates of perishables. Those rocks r god blessing for PL. Their going after silly farming, I am taking my rock radar
