Wordpress ecommerce pulgin

I need some one to install wordpress e-commerce and modify few thing as describe below instructions of e-commerce So when the user clicks “Buy Now” the credit card[use wp-ecommerce pulgin/paypal] should be processed, money taken from the purchasers car and deposited into our companies bank account. BUT the only people who can purchase from the website should be geographically isolated to the Redcliffe Peninsula as I have outlined previously. If the purchaser’s delivery address does not appear on a drop down, than an error notification should pop up stating that deliveries are only available at this stage exclusively within the Redcliffe Peninsula. A notification for a 48 hour delivery time should be sent along with a digital receipt of some sort to the purchaser and us alike so there are matching invoice dockets. The persons information and address should be collected so that the purchaser can have a user account. This will allow us to maximize data capturing here is url [login to view URL] we will provide wordpress theme. It's an urgent. For expert it is one day work.
