Pinecone is one of the best survey panels out there for earning fast cash, and they pay quickly — usually by the next day — for the surveys you complete. The surveys don't come every week, but it's a nice little bonus when they do because of how fast they pay. Right now Pinecone is open, but there is no guarantee you'll get in just depending on what demographic they need right now.
I recently gave some marketing tips to a bunch of local professional photographers who formed a company about 3 years ago. There are 7 of them and they were making around £400 a month (collectively). So I advised them to create a website, show their individual skills on the site, and start promoting themselves. (No no no, not the way you are already thinking!) The skills about their technical know-how, courses they can offer, and (very importantly) reviews of the latest equipment on the market.
Number one on the list is also the easiest survey site to sign up for. Once you're in you can take surveys and get paid at Survey Junkie. It's possible to make $100-300/week completing surveys on Survey Junkie! All you need to do is instantly qualify, then view exclusive offers in exchange for your opinions and get access to paid surveys, clinical trial opportunities, and other work offers. Survey Junkie’s interface is super smooth and intuitive (unlike the majority of survey company websites that look like they were built in 1997), and members are paid in cash via Paypal. Oh, and Survey Junkie also has an 8.9/10 rating on TrustPilot — the highest of any online survey company. This is one is the more reputable survey companies out there and I use it often.
