Betting exchange front-end code repost

Do you have experience or knowledge about betting exchanges? if not, Dont read further. Looking for somebody that know what back/lay means or may even have existing code related. If you do WRITE WHAT EXPERIENCE YOU HAVE IN RELATING TO THIS TASK, nothing else or you will not be considered. The requirement of this task is to develop a quick prototype with these elements: * Basic Web page divided into a menu section to the left, a odds section in the middle and a betting section to the right * Design is not important, just make it work Features: GET DATA FROM SERVER * Make a server request to get sportsdata (xml) upon start of script for use to the navigation system. LEFT SECTION - DISPLAY MENU * Display first level of this sportsdata (sports, e.g. Tennis, Soccer, Basketball....) LEFT SECTION - CLIENT NAVIGATION in menu * User can locally navigate in the menu without any server communication (java?) * User can expand/collapse level 1 to level3 (Soccer->League->Match) GET ODDS DATA FROM SERVER * When click on a match (level3), make a server request for oddsdata * Present these odds on screen in mid-section MID SECTION * Present these odds on screen in mid-section * Poll server for updated data every x second * On click copy data to right section (bet section) RIGHT SECTION (bet section) * Option to buy/sell the usual way (see attached) with level of odds * Option to send bet request to server. Wait for answer Technology like php/mysql/java/ajax preferred
