Build a Website

Hello, I am currently working on a new project involving paid memberships and need help getting my Wordpress site up and running. I am installing the following theme and will install as the demo template for you to work with: [login to view URL] What I need is for someone to create the back-end functionality i.e. payments. The theme has a nice pricing section that I would like to keep. This project will require you to get the payment functionality up and running and working 100%. Since this is a subscription business, this must include recurring payments. I prefer to handle all of this within a plugin that is used to manage these type of businesses. Once the user clicks the "buy" button on the monthly option that they'd like, I would like the recurring payments to be handled via Paypal. If this can be handled with a free plugin, that is preferred. But, if there is a paid plugin required for this, please let me know and I will buy the plugin necessary. The plugin MUST work with the theme provided and should preferably allow users the option to cancel their subscription at any time. Please provide any examples that you have of creating subscription focused sites. My max budget for this project is $200.00 USD.
