Design and build an online store

I need a website UI designed and fully implemented from start to finish. Will require use of OpenCart, HTML5, CSS, JS/jQuery, SQL perhaps more. UI will be worked on with another designer and our only requirement is no Wordpress. Any other CMS will be acceptable provided the framework allows us to complete the task at hand. We're working on a 50 day timeframe for the site to go live. Estimate 100 hours of work. Contact me if you think you have what it takes to get this done properly.
