Betting script

Hi, We need a sports betting site script similar to bet365.com. Here are some specific properties that we are looking for: *It must be written in php, open coded so that we can change the codes if we need. *We don't need graphic design. But you should put some graphics in order to show how the script is working. *Must be working with mysql database. *Must be an admin panel. And by using this admin panel, we have to be able to manually add new sports types, add dayly fixtures and betting ratios. and also admins shall see account histories clearly. *Must contain multiple bet options *Must support Java,Javascript and Ajax. Anyone that's has an already written script is welcome. This project is urgent. For further details please leave your pm.
