Basic Web Shopping Cart

Hi, I need a simple web page to permit users to search and find products; users can add some products to a shopping cart; when user finalize his work he confirms purchase and his order will be sent to a email address. Web page interface will be similar to eBay or osCommerce system but will be very much simpler. I DON'T provide graphical template, you will develop one. Web Page will be in PHP and interface with INTERBASE DB (archive with extension .gdb) I will provide database with products data (EXCEPT user information, you will create this table) How user will use web interface: 1. users can search products from a textbox, as first option 2. users can search navigating in categories tree list on left side of page Products than match search, will be showed with small image and some information (item name, description, and one or two additional fields) User can double click on image and browser will open a new tab showing a bigger photo and same information. Images are saved in BLOB filed If user IS LOGGED-IN with user/pass than page will change as follow: 1. system will show product price 2. will appear shopping cart icon near each product and user will able to select quantity for each product he select. 3. at the end of user selection user will confirm his purchase and an email will be sended to site administrator (with information of user, and items purchased: code, description, quantity and unit price) User can register in site completing this information: Name,surname,email address,phone number,name of company,password,captcha image System will be send an email confirmation to user with a confirmation link or [login to view URL] will click on link (or confirm his subscription typing code in site) and system will confirm his account is valid and send email to administrator User will be able to access and update its own information, including change password Will be appear ONLY products than have checked the database field Email to receive user registration or products purchase will be customizables from conf file. Categories list will be extensive. System will paginate products on various pages. (number of items for page will be customizable from conf file) Categories list will contain three levels (category and two subcategory) Please, contact me for any doubt about project
