Worldpay Integration(repost)

Currently my website processes payments using paypal and I want to replace this with Worldpay. The website is for a hotel and allows users to book a room online. It works like this: User selects date they want the room, room type and number of nights. If the room is available the user can then pay for the room online. Once the payment has been made, the reservation details are confirmed in the database and the booking marked as paid. Payment is currently taken using PayPal but I want to replace this with Worldpay. The website is built in PHP and MySQL. Please ask for any more details. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows?
