I want to build a website where 2 kinds of people will meet: survey posters-companies and survey takers-individuals. Posters will pay and individuls will earn. Companies will sign up, write brief introducion that survey takers will read, choose people who will take their survey by age, income, city, marital status, family size, gender, employment, and by ownership of certain things like car, house etc. Then they will pay using online payment like paypal, credit card and will choose the number of people who will take survey and survey size:big, medium, small. After that they will input questions and multiple choices, include free writing areas where they want etc. Then they will submit and wait.
The survey takers will sign up, fill in form with all the questions above like gender, age, income, marital status etc (same as above). Then they will include their e-mail and wait. When they are informed about new survey they will sign in, and take the survey and get paid by website money. When the website money reaches certain amount they can redeem. The number of people will be limited by first logged certain number that the company wants. For example if they want 1000 people to take their survey, first logged 1000 will take and those who are late will be told to wait. Or can change this part into better function. The difference between payment will be website's income.
