Website to sell music

So I'm planning to start a website to sell my rhythms. I checked other established websites like cashmoneyapbeats.com or taztaylorbeats.com, and I must say that they looked very clean and well made. Their sites have an identical structure, so I assume they are using some kind of design application, for example, Bandzoogle. Or maybe they both paid for the same designer who created their websites? How do I get a website like theirs? Thanks for the answers.
