I've got this idea recently, but I'm not sure if it can work and I could use some pro-tips and twists before I start working on it. I'm not sure if I should share it public or not, but I'm still a newbie and I trust this community...a bit I was thinking of making a site, where people would complete survey to win certain gifts. I googled a bit, but didn't really find something like this online. I got a sort of EMD domain in mind as well. The whole thing would work like this: Let's say I put up a contest for Mobile Phone. People would fill up a survey, and only after that they would be able to give me their email. I'd get money from completing surveys, which I'd spent for the mobile phone and keep rest as profit. Since I also got their emails, I could use it for future email marketing and build a solid list. Afterwards I could send them offers from ebay/amazon/whatever with the Mobile Phone (and other products). Few things I'm not sure about - how much $$$ do you make from one completed survey? Would I get enough money to buy the gifts as well? How many people would I need?... How do I content lock the email, after they complete survey? You know, window poping out with "give me your email" only after completing survey. Thank you.
