I need to build a Wordpress 3.1 compatible plugin that will let me charge the visitors for reading the post. I've attached a text file with detailed description and the graphics that will give you an idea how I want the plugin to work.
Please only bid if you have experience in building Wordpress plugins from the scratch. The project is not complicated but require sound knowledge of wordpress plugin development.
Please read the requirement carefully before you bid. Canned responses will be ignored.
