We are a company looking to get a digital store setup for selling a digital product. The products we would be selling are .zip files. Credit card processing, as well as check processing will need to be integrated into the cart system that is used. It is very important that the store looks very clean and sleek, web 2.0 if you will. Navigation will need to be simple and intuitive, with the library of products sortable by a number of criteria.
We would be open to having this done using Drupal + Ubercart, or another box solution, however it has to look highly customized and sleek. Meeting milestones and being confident in the proposed timeline will be very important for this project.
