Google Checkout Expert

This is third time I list the project and I hope this is my last... I have: - Custom shopping cart - SSL certificate; - Google Merchant account; - Google Sandbox account; - Almost all PHP examples which are found via Google; I need: - payment process not to finish at google checkout page (need to redirect user automatically back to my site, if you know paypal API, you should know for what I talking about); - auto charge the user (if possible); - of course I need the response from google; Also if it's not possible to pass the product details (some of the products on the site are generated after several steps, so they don't have Product ID) you should pass the hole card amount (include shipping) and no shipping costs to be added in google. You: - should not try to use domxml - will not work, we use PHP5; - should provide me working example; - should work without accessing our site (don't worry, I will give you all needed data); - can communicate via MSN, Skype, ICQ, Yahoo or GTalk; The job is simple for someone who already have experience with Google Checkout integration, so I expect result in next 24 hours.
