Surebets - getting and comparing odds from 5 websites

I want to have a software for searching odds from 5 bookmakers. (I will give you the urls in PM) THe software/program should be extremely fast. I dont care about design at all, the soft will be only for my personal use. The core of the project is GETTING odds (data) from 5 websites. Extremely fast, rapid and then comparing them. How you can get odds from bookmakers? In general you have two major options, first being making use of accessible xml-feeds provided by some bookmakers, second being manually scrapping odds directly from the website. First option is much easier, however second ensures rapid odds refreshing and presence of all available odds. In xml-files many bookmakers do not show all odds. Moreover xml-files are often not updated frequently, like every 15, 30 minutes, which for arbitrage player is not acceptable. So forget about xml files. I wil PM you a screenshot showing concept what I expect from you. The scanning must be very very fast and very reliable. I will pay you after a demo or trial version is provided. I will prefer person who have already done similar job. A demo must be provided before payment.
