Joomal Expert needed for website redesign & improvement's

Frontend requirements: I am looking to have a product showcase website using joomla with the following main features. 1. Front page with Images and Youtube video slideshow gallery like in front page of [login to view URL] (similar to the attachment "frontpage") 2. Main menu like on [login to view URL] with images and full product tree (Possibly using JA Mega Menu). 3. Product info page with image, video & flash gallery like in [login to view URL] (page similar to attachment: productpage) I want the full installation, setup configuration of the joomla website and customization of templates with menus & modules as required. I will provide with detailed explaination of the requirement and with the menu & pages tree for you to configure the website. You would be only creating the basic framework for the website and I will add the content and images later. I would prefer using the template "intermezzo" for joomla and I have already purchased it. All suggestions honored though. Shopping cart: The website also needs to have an online store, with an interactive order building tool that selects components from a list to build an order. ( Example like in dominos website) The order is priced as the components are added and order image is sent to the backend customers profile along with order details) ( Possibly using FLEX) Backend: Linked to the online store, we need a very easy to use backend tool where we can manage all the customer and order details including Customer info Quotes (Send custom quotes to a customer and prices would be saved to customers profile) Order specifics(generated from the order building tool) Orders (view/modify orders) Invoices ( created automatically and manually) Shipping tool (to create shipping labels and save shipping info & tracking #s to the customers history) Emails(Send/view threads of emails communication with the customer) Comments(to add internal comments about the customer) Payments (To recieve and manage payments for orders) Backup database (All the above customer & order details should be manageable on a single page with tabs for each of it. Possibly using AJAX)
