Custom made shopping cart

I am looking for a real professionals to build custom website shop based on my mock up design. The website is currently based on Moonfruit system, but will be moved to Joomla or Wordpress. Please see the design of the shop on this hidden links: [login to view URL] [login to view URL] Here are some clarifications: . it is not a functioning shop, just a mock up on how it should look like . airport selection should not load a new page but change within the same page . when you click on 'find out more' it should open more information part (just slide down) . Car selection is the most complicated one, other products should just have a simple text, link box. . at the moment only Stansted and Heathrow are build, but other tabs will be very similar . anything bellow 'choose additional items' will remain at the same, hence should not be affected by different airport tabs. . every click on radio and tick button should automatically calculate total for the cart at the top . part of the design should be a build back end: how orders are passed on, saved to history, automatically confirmed to the client. . Shop should be connected to PayPal and credit card (your suggestion on the best system is welcome) . Attention to detail is very important in terms of design and functionality. Additional details can be discussed later. . Pictures and text box should be adjustable from control panel without additional IT support (e.g. to change prices, pictures, name of the product) I understand this is not a small project, but for me priority is on quality, then price and only then time. Your suggestions on design, or how to make it better functioning or cheaper is welcome. When quoting please consider, that we will have adjustments to this project, as well as other company projects. Hence this is not one off job, but potentially long term partnership. I look forward to hearing your thoughts.
