Expert Customization Oscommerce

***NOTE*** This project is being reposted after being cheated by previous Provider 'oscsupports'. Full payment will only be done by Escrow only after project is truly done!!! This will avoid getting cheated again ***NOTE*** I need someone that is REALLY GOOD with PHP and has time NOW so we can do some serious programming/customization on Oscommerce website. This website will be done from scratch. I have only installed the basic layout and I want great changes to occur. Also I would like the job to be done in maximum of 15 days. I will be permanently available online (MSN) to monitor and answer your questions whenever needed. Please show me some previous work on Oscommerce. (complex works please, not standard implementation) The hightlights of this project will be: -Modifying Categories and Subcategories appearance When you click on categorie it will NOT unfold subcategories. Subcategories will be directly shown in the main frame. Once you click on 1 of the subcategories oscommerce will show directly the product listings so subcategories isn't visible. I would like this to change: When you click a subcategories, they all remain visible and underneath you see the product listing of the subcategorie. -Making URL show directly on product_info page. Instead of putting product_description (html) I would simply like it to fetch the url and display it fully as product_description. This URL page is preformatted and will show correctly for each product. - Product Options as individual products I would like to add product options below some productpages but with a shop cart next to it. All those options are also products and have their own product_model number. It is different from the standard oscommerce option showing just an options with no product_model available! - Display product shippingcosts after each drop in the cart. (NO login required yet!) - On account information I would like to separate street from streetnumber. Streetnumber should be added to an individual table and considered as integer! -Create header with possibility of different tabs. Each tab having a pulldown menu showing categories. Each tab will make oscommerce change layout color once pressed - On mainpage when 'details' is pressed under a product then frame should appear and blackout the background. Inside frame customer can decide to 'close' or 'add to basket'. Either action done frame will close and all is visible again. -There should be on each [login to view URL] an invisible little frame that will show a standard 'new' 'special' 'great offer' or anything else message in red. This can go 'on' and 'off' according to the settings. This way I can randomize specials automatically. -Randomize specials It only needs to show a sign 'specials' in red and the price becomes red. No percentage or what so ever applied! Simply glowing to attract customers attention - Customize shipping and pickup fee When COD (charged on delivery) I would like the customer to pay 10% of the total order upfront. This should be shown on the invoice while checking out so customer knows what should be paid. - Communication interface from the website. Customers can send messages by entering ordernumber/email and password (account registration) -Integration of contributions: PC Creator, RMA Returns, Newsletter and Poll, header tag control -Web promoting for good indexing on search engines! -Good and creative design incl. logo and header. I have some example of what I want if you need them as reference to build up an idea. Please do NOT send in some standard messages. PLEASE START YOUR FIRST MESSAGE by mentionning ''Bid for Project001'' This will allow me to know that you are not sending an automatic bid. Only messages starting with ''Bid for Project002'' will get a 100% reply!! GOOD LUCK!!
