Minecraft shop page?

I'm looking for a website where you can simply install and after installation you can create an admin product and they are then simply displayed for normal users. The site should support paypal and paygol. For example, if you buy a rank you should get it within 10 minutes. I know there's buycraft but we want to have everything in our own hands. It may also cost something.

DeinPlugin.net offers one - I just don't know how good it is.
