Searching for Cash Surveys

Previously, I signed up with a lot of survey companies, but because of being in school, I ended up not being able to do most of them. Now I have time and would like to revisit those companies. I am going to search through my email and read the fine print. One of the ones I re-read about yesterday offers prizes for doing surveys, and although that is nice, I just really want cash for doing them right now. Cash is what I need to pay off debt and to save. So, I guess I will just keep searching through my old mail. I know with some companies, you can redeem points for cash, but I just haven't stumbled on them and figured it out yet.
