I need to add two pieces of functionality to an existing joomla web page.
1 - A full forum installation and setup.
2 - We need to be able to sell several PDF files for download, we have a merchant account but need you to set it up. We would like our customers to be able to select a PDF file to purchase. After they enter their credit card information, the payment is processed and then the PDF file is delivered either on the web page itself or through a link sent to their email automatically.
