Institutions/individuals that understand the international financial intricacies of introducing a Bitcoin exchange in a central african country in order to setup a market for Bitcoin in the local currency and have a strategy for investing the local currency into a local industry that manufactures an exportable product whose proceeds can be realized in another country that has the foreign currency required to repatriate the profits back to the institutional/individual investors' home base.
Sounds like a really big plan.
With pessimistic feelings I'm not so sure you'll find someone who meets your qualifications in this forum.
As for businesses involving the government, I think it should start with building connections with relevant government people first, this will make the process of legality and legitimacy smoother. It also avoids wasted effort when you've gotten a few steps with someone experienced in this field but ultimately doesn't get support from the government.
The country is in fact central africa in which cryptocurrency is still unregulated. Its very conducive for crypto investors.
Afaik, bitcoin is legal in central Africa
