Joomla Story Website Help needed

Hi, I need help with my joomla 1.6 website. I just want some extensions added so that people can pay to join a certain section of it. The site will have two groups of people, one group who upload stories and the readers who must pay to download the stories. I would like to use Tinypass for the readers. It is a simple task to add these extensions to my website. I don't need it to look amazing, just working. Thanks
