part time jobs - paid survey lists providers

Many middleman web sites have cropped up which tell you that you can make thousands of dollars on online paid surveys by following their advice.
On payment of fees or subscription, they usually give you a list of the online paid survey companies.
These middleman sites hype about huge income, which is not true.
You have to be again careful about the list given by them as the list may contain mostly scam sites for which the middleman site may be an affiliate.
I give below another link to another market research firm.

This online paid survey firm offers market points for completed paid surveys , which can be redeemed for cash.
