Need Joomla Paypal Automated Download after Purchase

I have a Joomla site that will be setup already. I need somebody to install a module that will allow me to add products that when clicked on, will direct the purchaser to paypal for payment. As soon as payment is received, a download link will be provided so that the purchaser can download the product they purchased. This could also be emailed to them, whichever works. In this case, they will be provided a link to a video to tutorial video download. This is for a bookkeeping company that will have tutorial videos. There will only be a few products, but each purchase needs to link directly to the product purchased. You will be responsible for: 1) Setting up module 2) Integrating it into the site 3) Providing an example product that works with the site owner's paypal 4) Changing color/font type of module to match the site Once you've completed that, as long as you show me (limited programming knowledge, medium Joomla knowledge) how to add new products and make them show up, the project will be closed. I'm only looking for bidders with good feedback, as payment processing is sensitive info.
