Google Checkout Implementation onto an existing private cart

The project is very simple for someone who has done a Google Notification API Checkout previously. So, if you cannot show me at least one or two Google carts that you have already done, please do not respond. Thank you. a) I have developed a paypal cart for event ticketing from my site. The paypal button code is built from database data. I am giving the exact paypal button code below and I want the Google cart implemented using the values in my database. Additionally, I will need to capture some basic customer data before the customer is taken to Google pages for final payment. b) I will share the database tables and structure with the person who gets the bid. c) I think this will not take more than 3-4 hours for a person who has done this. So, I expect a 24 hour turnaround max for this. d) All code files/classes/functions will become the deliverable and will become my property. e) Payment through Escrow only please. f) You can be anywhere, but should be contactable on Yahoo Messenger or Google Talk. g) Please quote only below $80-100. Any bids more than that will be rejected.
