E-commerce website to download market reports (PDF)

Project Description:
Need to create a website/portal where we will be sellling - Market reports online in PDF format for DOWNLOAD.

Download features should be similar to this: http://www.euromonitor.com/consumer-electronics

Steps:
- User should see the full list of items to download
- Select one report and able to see a small sample/table of contents
- Add to cart (pay via creditcard or paypal)
- After payment, they should be able to download the report.

* We want a simple click, pay and download process and do not need to keep clients' profile (optional).
* Site design needs to be clean and simple, nothing complicated. Corporate look, white, black, grey.

Initially you would upload few reports but in the end we will upload and manage reports so the process has to be simple.

HOW I WILL SELECT
- Please include the link(s) to your best e-commerce works
- Which software/CMS you use
- Proposal if any
