Dayo, sadly, because of the market size, app related business remain only profitable in a few western countries. I don’t know of any that could be used in Nigeria. That said, you can always put your own twist on things and make something that people in your local area could find useful. Essentially, you create a niche market out of it, and that can be very profitable.
Nick Reese has done an incredible job of building websites, developing outstanding searchable content and selling other people’s products on his sites. He gets a commission on every sale or lead he sends to the company. So he never had to create his own product in order to build his business (he has since branched out into other areas that you can check out on his new site). Pat Flynn also does an amazing job at this, and he actually shows how much he generates on a monthly basis from his affiliates here.
I really don’t want to chat, receive or make calls (I have a kid and baby I don’t have no silent place to work and also because I’m not a calm person I get mad easily fast), I don’t want to go out at my home because of doing a “job”, don’t want to do survey, I don’t want to write or share my thoughts or anything like that, I don’t want sell anything either.
