Client asked us to develop a BlackBerry application as well as a website which will allow the advertisers to post their ads and will also help BlackBerry users to view the ads via push notification. He told add functionalities so that the admin of the website can manage features and web services are required for an interaction between the web interface and the application. In this site advertiser can add fund against the advertisement upload. User can add the fund in own account using the payment gateway. He also told us to allow admin to manage the CMS content of the site.
