Hi,
I'm a professional software developer. I have worked on a bitcoin mining pool website and i know how to setup wallets and generate addressees for transactions. Further more, i'm a web programmer and i can make the site for you. I can see that bitcoinroll is using node.js with websocket to push status on the front page. This site is pretty easy to make, it just takes time. You will need a VPS hosting to host the virtual wallet and to use api with bitcoind (linux). Please contact me for more info or with any question that you have.
Looking forward in working with you,
ivan R.
