Easy PHP project - Online order form

The project is very easy. First, we need an online page where the administrator can add/delete/edit the list of product names of our catalogue. Then, we need an online page in wich the salesman login, and are able to: - insert the list of desired products (chosen among the catalogue), as well as product quantity, and the price the customer pays them and the % the salesman gets on that product. (salesman are trusted people who will insert real price and %, no need to check these fields). Salesman will also insert the shipping cost and details. - the customer's details for invoice - extra notes, details,etc field The salesmen then clicks the button SEND, the page will calculate the total invoice cost, and ask for confirm. If salesman confirm, the order will be sent by email to our office. All orders will have a number to identify them.
