I have installed a e-commerce store and most of teh work is done. It is open source PHP/MySql and the name of the shopping cart is prestashop. I basciaaly need someone to integrate with Google Checkout. It should be faily straightforward. I already have integration with PayPal and google has lots of documentation and sample code. I am not doing it because I have to concentrate my time on other business activities. I reckon it shouldnt take more than 4 hours of work.
