Build an Online Store

Hello, My branch of business is selling online games services (such as ranking up accounts and coaching), we also got into account reselling and we're looking to build a more automated webshop for it. My website runs on Wordpress. This is currently our account shop: [login to view URL] We're looking into replicating something like [login to view URL] Pretty much the exact same deal (ofcourse some color changes and a couple of design tweaks, nothing major). NOTE: I do not need a whole new website, I need this "account shop" implemented into an already existing website of mine. Everything under the blue picture slider is what I need, only the things from the frontpage under the picture slider, the rest is already present in my existing website. They only sell in PayPal but I want to sell with PayPal primarily, secondarily Bitcoin and Skrill. Basically, I need to be able to create a "product" (account) in my Wordpress plugin (Woocommerce, or propose an alternative), with specific details (I will provide the list of details), such as how much gold the account has or what is it's current rank. After the product has been created, the product pops in the website and client can checkout and purchase it just like on the lol-smurfs website, after a succesful payment he will get his account delivered to his email and the account sold is automatically removed from the website. Everything ofcourse needs to be fully responsive and usable on mobile devices. NOTE: I will only choose freelancers who show they are serious and deliver design specifications or a demo website to see how it would look.
