It's not a ton of money, but I usually make anywhere from $50-150 a month between online surveys and local focus groups. You can easily do a google search for focus groups in your area. Around here there's a company called Fieldwork and I know they have offices in other states. There are lots of market research firms out there that pay pretty well for an hour or two of your time to go in for a focus group and lots of online survey companies that pay a little for quick surveys or more for online focus groups. The thing to watch out for with the online companies is making sure you don't pay a dime. If they ask YOU for any money, it's not legit and you absolutely don't have to pay for a list of survey sites - the info is all out there for free online.
