I have a client that needs an ecommerce solution. The site has been designed in wordpress, but we are re-thinking the platform. They are attempting to sell access to pdfs. A member will pay a subscription to have access to one of the pdfs that they choose. Each month they will be able to choose one more pdf. The pdfs need to be viewable online, but not printable. Does anyone know the best platform to build this site in to allow the flexibility in pricing the client requires, or can anyone suggest a wordpress plugin capable of delivering the same. This project is urgent. The client is willing to pay a reasonable amount so please contact me with quotes and timeframes or any suggestions. Thank You.
