Costruire un Negozio Online

I want a site similar to [login to view URL] I know that is based on wordpress and this theme [login to view URL] I'll provide both. What I need is to show the prices also on bitcoin and litecoin and add the gateway for them, without using any external gateway processor, but simply using bitcoin and litecoin API, just like [login to view URL] does. Please give a look to it before making offers. My budget is 200$.
