How to use perfect participle accurately?

While I was writing an essay, my argument was pharmaceutical companies should provide under-developed countries with medicine at a relatively lower cost with minimum profit margins. By doing so, they could improve their net profit while helping poor nations as such actions might make it possible for the citizens of such countries afford them. However, if they do not do that, they could not sell their products in such countries at all due to the financial constraints.

Bearing this in mind, please someone let me know whether the following sentence is grammatically correct and natural. My main concern is that whether it is feasible to use present participle under such circumstances.

In other words, having given some discounts for less-wealthy countries, they could make it possible to sell their products which might be next to impossible with normal price.
