Its a very simple work. You have to use sql queries to retrieve data from the database and display it on a webpage based on user query. for example, if user wants all prepaid plans of an operator for a particular city , u'll just have to write a query that retrieves it and displays it in a proper format in the webpage. So basically it is a webpage tat gets the user inputs and displays results based on their input.
Will need the work to be done in a couple of days.
