Create an order confirmation page with google analytics conversion tracking code

Hi there,

I am looking for someone to set up a page where I can insert my google analytics conversion tracking code so that google registers every sale made through my website.

Currently, google analytics is only tracking sales made via PayPal. Customers can also pay using WorldPay, which directs the customer offsite to carry out the transaction. Google does not appear to be tracking these sales. I have been advised by WorldPay to create a page that the customer is redirected back to after the payment has been made, which includes the google analytics tracking, so google can recognise that a sale has been made.

I hope you can help me with this and I have explained it well enough! Please advise on if you can help and a quote.
