Guys, I need your input here.

Someone wants to transfer funds to me from the USA. We do business.

Using their banks in the USA will mean a delay of 1 - 5 days and it's not convenient.

Using worldremit means the person can't transfer above 5,000 dollars per day.

Using xe.com (which accommodates as much as you can send) can't transfer to your dollar account in Nigeria. It only converts to Naira at official rate, meaning I'll lose money here.

Using Chipper Cash came to mind but I'll receive naira in official rate. I need to receive dollars and change at black market rates.

Please, what's the way forward. I desperately need a solution, guys.
