Suggestions for Digital Download eCommerce solution

I’m having trouble figuring out what CMS or Cart I want to use for my website that will sell digital downloads. I will be selling .zip files with samples and or synth presets to music producers. It will be similar to Loopmasters or [URL=“”]Sounds To Sample. Is there any way you guys can figure out what they used?

Features I will need:
-Cart or CMS that’s design is 100% customizable
-Link Protection
-Download limits (file can be downloaded up to 3 times up to 72 hours after purchase then the links die, for example)
-Audio Previews for products
-Simple way of adding products
-Complete PayPal integration (Maybe WorldPay too in the future)
-Customer login system
-Real time tracking of sales
-SEO integration

I will outsource this project to a freelancer but I figured I could save money by figuring out the system I’m going to use first, and have them do the design instead of the whole thing.

What would you guys say are my best options? Or would you guys suggest I have somebody design a system specific to our needs? $750 is probably the most my budget can handle.

Thanks a ton!


How will you be getting paid? The reason I am asking - you might check out - they are compatible with PayPal and can offer you different options.
