We are looking for someone who can set up a freshly-installed Magento system to work with downloadable files (i.e., a computer program or a specific .pdf file). Specifically we need the following:
1) Configure Magento to work with this type of file, including, if possible, sending the purchaser an expiring (time-based or hits-based) download link on receipt of payment.
2) Also configure it to work with an example PayPal account (we will replace with our credentials) as well as common credit cards, those being Visa, MasterCard, and AmEx.
3) Most importantly: document the precise steps taken, i.e., keep a log or journal. Magento is deliberately obtuse and difficult, and we need a competent log of what was done.
