I wouldn't waste your money. The only people who make money from this are the ones who charge $39.
I sometimes do online surveys with ciao.co.uk but if you qualify to actually take part in the survey, the pay is ridiculous about 10-50p per survey.
Last year I applied to a company that provides answers to people's questions via text messaging. For some reason they turned me down, but I may apply again, they pay 35p per answer provided, but to make something of a living, you would have to be online all day.
