Customisation of Joomla component

Hi, I need customisation of a Joomla Component, called Joomla Quiz Deluxe [login to view URL] Please refer to [login to view URL] , create a login id and take a free simulation exam. I saw that they are also using Joomla Quiz Deluxe and liked the customised component. It had some feature which is not present in the current component - it was opening in new window - copying was not allowed - had mark/unmark feature - had grid feature, where you can view the questions I want these features and need an additional customization where the entire quiz is divided into 10 section and the user have the option to go to any option and attempt question from that section. This is a high priority requirement, only serious bidders apply. Note: Only those who have previous experience in customisation should apply. For any more information, please PM me. Thanks Ratan
