(Not a big fan of dirty today, sorry)
Vindale Research is an online company that takes an interesting approach to market research and online surveys. They advertise payouts of $5 - $75, a rate considerably higher than most competitors and state that customers will be evaluating products and services.
In reality, You may get there one day, but starting off, You'll be making between $0.10 (To complete the profile/demographic questions that most companies expect you to do for free) and $4.00 per survey ($3 is about the average for 20-30 minutes). The more you do, the more surveys you will get invitations to, and the higher they start paying. Lately, I've been getting offers for some that are upwards of $10, for about 30-45 minutes of "work".
