ecommerce order process pages need changing/updating

Our website: [login to view URL] Once a customer places an order on one of the categories by clicking 'buy now' i want the the following processes to be implemented; 1. Use the calculator to select price - they click 'order now' 2. new page to ask them if they want a free file review, or if they would like a graphic design service. the graphic design service would need to be a drop down menu so they can select, product ordering, size of paper, number of sides. then it would show them the price, to which they add that to the cart. The page would then show them an updated total for their order and they would then continue to step 3. 3. new page which says a) login - boxes for username and password b) i am a new customer - box to click to take them to add their details c) i forgot mypassword d) continue shopping this above step has already half been completed however the buttons do not work for internet explorer - you will need to modify and update this page: [login to view URL] 4. if they select a - c the screen then takes them to the order process page: (all of the below would be on 1 page) which will show the following; a) production selection which will include all the details of the product they have ordered and the delivery option they have seleceted. b) discount code box and then a button for submit - or use the same php that my site already has which has an auto update i think c) upload files - up to 4 files d) total price e) input delivery address (option to have same as billing address) f) payment options - paypal or bank transfer g) confirm terms and conditions h) submit order a good example of what i want is on [login to view URL] - i have a dummy account on there of username: danielprinter password: printer i like there account login page, their order page, and their file review page (which we would have as a file review and graphic design page) you can also see the order process on my website as it is by using the below dummy login; username: ask for this password: ask for this you will be able to complete this in a short space of time, and be confident that you can do it well - and that you understand what i want. please do not send a standard copy and paste email as I will ignore your bid.
