Remember when I said that you have to build up to 1000 HITs to get the good HITs? The right kind of penny and cent HITs are money makers. Some of those penny HITs are as simple as asking you whether there's a particular object in a picture and you answer Yes or No with a radio button. You can use a script that automatically centers the photo and assigns keyboard keys to the Yes and No options and Submit button.
Let's say you that you're of average speed and can only do one every three seconds.
.01¢ * 20 HITs * 60 minutes = $12/HR
Let's say you modify the script a step further to where it automatically submits the HIT when you press a key for your answer. You could probably do 35 to 40 a minute.
.01¢ * 35 HITs * 60 minutes = $21/HR or .01¢ X 40 HITs * 60 minutes = $24/HR
This is the results of one of my regular days doing surveys. Notice my mouse cursor on the right hovering over the hourly rate.
This is one of those unicorn (requester's hits that so good that you do everything to keep them a secret) batch days. I have to obfuscate the requester's name.
