Simple PayPal Shopping cart - repost

I have a very simple requirement - please do not read more into this project. Also please provide me examples of similar work you have done. Don't waste time for both of us - if you haven't done the work, don't bid. If you've done this work, just give me a couple of your best examples - I don't have time to read through a long portfolio list. I have a need for PayPal coding for a Wordpress blog. There are two products (books). One is priced at £9.99 and the other is priced at £11.99. Customers may buy one product or the other. In some cases they may by one of each. Very rarely they will buy multiple copies. There is a shipping charge of £2.50 per item purchased. There are no taxes. The code needs to: - allow the customer to select the product and quantity of products - calculate shipping costs - transfer the customer to the PayPal site for purchase and checkout - return the customer to an existing successful or failure page This is literally 1 hour of work and the deliverable will be a few lines of code. Please supply examples of your similar past work along with your bid.
