K2 Articles - Create Subscription Service Component

I would like a component / Plugin created that works with K2 Articles component so that users can subscribe and pay for content based on category and specific users. Functionality: - A user signs up and initially can view 'free' k2 content / articles - They can then choose to subscribe to various content via a button in their profile (also promoted on signup) - There will be a payment gateway choice such as PayPal and all major cards - There will be different price variables dependent on subscription duration and users / content (like a basket) - The user is invoiced etc and details of their subscription will be in their profile - The user can now access and view the articles they subscribed to **This could potentially be integrated with Virtuemart, so that subscriptions are listed as products.** ** End component / plugin cannot be re-distributed ** Please review temp site [login to view URL] atome [login to view URL] / egresearch/ [delete spaces]
