Odds Comparison Tool

I need a web based betting odds comparison tool.? Example sites are? ? <[login to view URL]> <[login to view URL]> The sites to which this script is to be deployed are both cms based with a left side bar , centre and right side bar. ? One of which is drupal based. I would like a drop down menu as in betbrain top left, which can select the sport, event, date or as a search. This would be based on the left side bar. When event is selected i would like the odds comparsion to appear in the centre content. There are currently about 10 bookmaker odds i would like to be used. Please ask for more clarification as to which bookmakers if this a problem. The data can be collected by xml feed ( each bookmaker releases odds in xml feeds), rss or screen scraping, however i would prefer xml so that it is easy to maintain if a bookmaker changes their site. When drilled down i would like each bookmaker link to have our affilaite id attatched.
