Urgent CGI scripting required - 6202

We have a small job needing a cgi-script. Here are the details: The job is for a very simple online shop, we have set up the shop page which has 10 products, what we need the script to do is when you click on the buy now buttons the information on the product is to be fed through to the next page which then displays the product details, adds on delivery (always £4.50) and the user is asked for an address, a delivery address etc. Once they submit this page, the data needs to be passed on to WorldPay where the customer can pay online and then the order details need to be e-mailed to our client. This is a small but very urgent job and needs doing in the next couple of days. Please supply us with examples of your work and an estimated quote.
