How can i pay someone in cents & they can withdraw when its $1

I have few freelance friends that want to work from home & they approached me saying if they can do anything for me. now I thought why not use them to post on my site & I will pay them 30 C per post, now my question is, is there any payment service online that can let me pay in cents & they can only withdraw the money when it reaches the $1.

this is because when they will see, their money is there & they have to do more tasks to reach the $1 threshold, this way they are more likely to stay…
