Hi @guerkhor,
You can try posting for Developer Wanted in the forum: https://forum.openzeppelin.com/tag/developer-wanted
You should also try other Ethereum developer communities such as ETH Global Discord and Crypto Devs.
You may want to look at other stable coin projects, including those operating in Africa, to see if you could partner with them.
Could you use an existing stable coin, see Points to consider when creating a fungible token (ERC20, ERC777)
