I've found Clickworker. It's an app where you earn money on the side with surveys, app tests, taking pics or short videos, etc.

Clickworker is a great company to keep in mind whenever you need some extra income or are in between jobs. ... Income potential is based on how fast you are able to complete each task (as well as the availability of work provided. Earnings on these tasks ranges from $15-$25 and above.

You also earn $5 on each referral or invites you make !!!.

You don't have to worry about their payment, clickworker has convenient methods of disbursing earnings even as a Nigerian; like PayPal, payoneer, or bank transfers.
