On average how much would you pay for a person? $5 or $10, what would be your offer to a person? Just want your honest opinion, because it sounds logical but how are you going to track 1000 people if they are going to buy your product or not? What if they take the money, signup, and leave???
The cost is very low through services like Mechanical Turk. Typically you'd ask them to complete a survey on usability of your site -- you get some useful feedback from them, and sometimes they return as users themselves.
But do you get paying users from a site like that? If I'm anonymously filling out surveys for $4 per hour I'm probably not in the target audience for your $10 per month SaaS service or a particularly prolific purchaser via affiliate links.
Does anyone have any actual success stories in that area?
