Clean, Professional, Website w/Shopping Cart

Hi there, I need a website similar to [login to view URL](will reveal once I select the coder)The website sells air purifiers. It should have all the functionality that the above mentioned site has and should be search engine [login to view URL] design should however be better! The graphics should be beautiful , yet professional. The theme is as you can see: Clean air, pure air , green etc...so try to have a amazing theme around these colours/images etc. My website will be essentially carrying the same products. The menu can be on the side or on the top...depends on your theme. I'll let you know what the menu items are...but for starting you can have the same items as [login to view URL] I need this ASAP. Let me know if you can design a slick looking, functional and SEO website with your price. Thanks
