Here is a link to some of my best survey websites: http://katykicker.com/katykickers-favourite-websites/
I am the self appointed guru of surveys as I make a LOT of money from them, I'm talking £1000s a year.
These posts should help a little:

http://katykicker.com/how-to-avoid-survey-disqualifications/
There are a LOT of legitimate websites out there, on my website I talk specifically about websites that I use, what the payout is, how long it takes me to reach it.
Before someone else comes along and says it I will let you know I've got fab survey demographics and I make more money than most, however most people, regardless of demographics, can make SOME money from surveys.
It will be time consuming and boring at times but you can pick up and put down survey sites as and when it suits you and I work solely from home thanks to websites offering surveys and other moneymaking avenues.
There are lots of other avenues to explore that aren't paid surveys and here are some money shed links you may find useful:
