HTML5 web site

I need a simple HTML5 web site to be developed. I need to sell a couple of libraries for software developers. So I'd invite all who are experienced in HTML5 development (this includes HTML, CSS, Javascript, AJAX, PHP, and may be some SQL expertise). There are no complexities, just plain content and some navigation items (buttons/tabs/menus etc.,). Not much graphics either. However I might care about the speed and simplicity and cleanliness of interface. Here's what I need: 1. Home page with some summary of what we do, and what our products are, and so on. 2. Global navigation bar (that is accessible in all [may be five] pages) 3. Integrate with paypal for payments ([login to view URL]) and when the customer pays, paypal should redirect the user to our website where we provide secure download of the product we're selling. 4. A way for the users to register and login (so they can view the products they bought and later on access to support on the products). I'm willing to move this to 2nd phase. I am a developer myself, and I'm fairly familiar with HTML5 and other web technology. I just don't have enough time to deal with the website development. So you can expect more technical inputs, and suggestions on HOW YOU CODE. So if you have some previous work to show off please let me know. I don't want to baby sit anyone at this point (although I love freshers), if you are a fresher and want this project, cook-up some mock-up and prove that you can do this independently. As for the design, I need you to come up with simple, and good design ideas. The key to win this project is CLEAN and responsive UI (with almost no graphics) and CLEAN CODE. Feel free to ask me for clarifications. Look forward to hearing from you all.
