How much extra money are you aiming for?
If you're not the nervous type and can speak clearly, there's high paid surveys/interviews that pay well. None of that .50 cent to few dollar crap either.
I have another survey on the 3rd from another site paying $25 for 20 minutes and one on the 4th paying $200 for an hour and a half with a bonus.
I make around 2K a month doing this for less than 15 hours a month. In the image above, these are remote surveys from one of the sites that I'm a member. The in person surveys and focus groups pay a lot more. What's even more surprising is that every blue moon, you'll get a weird one that will pay out of this world. The week before last, I got paid for an in home survey that shipped a cardboard box the size of a washing machine for a "Did you have mold in your apartment due to it being caused by a washing machine". All I had to do was take four pictures of the cardboard box, upload them and do a 30 minute discussion over the telephone a few days later. It paid $350.
If you're in or close to a major metropolitan area, consider yourself lucky if you fit the right profile for the in person and focus groups.

The below is an example of some of the surveys that are available on another site I'm a member of. Someone mentioned that they worked for Lyft. $100 for 45 minutes for the "Benefits Platform Feedback" interview. No PayPal
. The pay via Amazon Gift Cards. I know how to transfer AGCs to PayPal but I'm not about to reveal that in public so as to make Amazon aware and close the loophole.

Two of the websites pay me for referrals. That pays me about an addition 800 to 1K a month on average when I drop a link somewhere where one of the surveys fits the content of the page.
