How much does it cost to create a love calculator like http://www.loveyousweetheart.com/lovecalculator.php and integrate it into facebook as application. People can calculate and post this in their wall or friends wall. There will be link to the app in the result posted at wall. Application can be bookmarked. PM me the cost. Thanks. --more info: the script for calculator is already made. Just need to work on facebook integration.
