Beting application - open to bidding

Hello We are currently looking for the development of a betting application to use in computers in our kiosks. We currently have the database admin app, so all the betting, risk management, users etc etc is already done. We need a an application able to communicate with our existing solution, and able to use bill acceptors, so users can directly pay and bet in the kiosk. We can show you a sample working app of the competition, to get the idea. To have a general idea you can also look at siskowin.com. Something like that will be needed but as an app. Thanks
