Build a Website (purshase game currency)

I need a simple, fast, userfriendly and clean website. The propose of the site is to sell and buy online currency of a game, or game credits. We sell it in the game with our characters, but the transaction needs to be done in a website. Website to sell virtual currency of the game in Euros and Dollars, or maybe with Bitcoin as well. Able to create accounts to purchase. Able to apply discounts if we want to. SEO optimized. Chat online. IP tracking. Sections: - Home - Buy - Sell - Contact us - Delivery - Terms & Conditons - Privacy policy To purchase (buy page): - In game nickname - First and Last name - E-mail - Phone number - Confirmation Code Please, this is a really simple website with simple design (I can help with that), the main target is to build the infrastructure secure and safe for me, and for the user. This would be a really simple job I think, so send me your best prices.
