PayPal Website Payments Pro UK Intergration

Hello, I am looking for an experience developer with a lot of experience with PayPal Website Payments Pro UK Integration. You will be required to make an entire checkout system that works with our current shopping cart. I would like the checkout similar to the one here: [login to view URL] You will have to integrate both websites payments pro and paypal express checkout. You will be required to build a payment notification system. I would like you to set up the checkout so it works etc and inserts the data from a temporary shopping cart into a new permanent one. once notice of successful payment is received the database must be auto updated. * You must be very experienced with Paypal Website Payments Pro UK. Which is different from the US version* This project will use PHP but also Javascript to remove the options when a user is going through express checkout and auto populate some forms. Full project details will be given to the winning bidder and all instructions must be followed exactly. I will escrow funds before the project is complete but will not release them until i have tested the files. Thank you
