Best if you can develop your own site for this. Use the links posted above to get an idea about how it should look and work. Best again would be to hire a developer who has experience in this.
You can find a number of Paid to click offers from the sites listed under "Micro Earnings". I havent seen one where you can pose as the person giving the tasks because these sites are filled with users trying to solve these tasks and get paid while the site owners is simply embedding the tasks widgets on their site. Even the task providers are completely different.
So if you want to "turn the tables" develop your own site. Marketing that to public to get traffic is another story.
EDIT: My bad, didnt notice your post properly. Post edited accordingly.
