You don't need a tool, you need a good strategy. You have few products ready to be sold, so, to complete the process you need a traffic and conversion. You can have some paid traffic from social networks, search engines, forums and other advertising websites. For the conversion you need a well built website and attracting products that your visitors will want to buy.

I used to have fun doing surveys while I watched TV. I was choosy about the companies I used and I never paid to sign up for any. I got about $25 in free BlockBuster movie coupons, cashed out about $25 from another site and did an in house project trial where a company sent me to full size body lotions to use and record information about. I had fun, felt like my input was improving the business world, but I wasn’t looking to get rich quick, just earn a little bit in time that typically wasted. Some survey companies pay very little, others pay better. Of course, it is not fair to the businesses conducting the research to lie in order to qualify for a survey and they certainly deserve honest and thoughtful answers to their questions. The companies I worked with told me how much the survey would pay and how long it would it would take. Research for the reputable companies.
