Question
I have an online business designed to sell building materials to Ghanaians living in the US, Canada, UK etc who have building projects in Ghana, and I need a strategy for expansion and growth.
Answer
If I understand correctly you are from Ghana. And you claim there are Ghanaians that have settled abroad and have building projects in Ghana.
Obviously if they live abroad they have
-a local agent or representative
-they work through local banks
-they need licences (regulation) from federal and regional government.
that's where your prospectus clients are and that is where you should be looking
good luck
