499567 Virtuemart browse page change

Hello, we need to slightly change Virtuemart BROWSE PAGE. A customer have to have an option to use checkbox (simply check/uncheck) to add "home delivery" of a product. If a customer checks the checkbox, the price for 1 piece of product will change immediately on the browse page. The product name in the shopping cart should be also different if the customer checks the "home delivery" or not. Thank you for your bids.
