When we where looking at Kiosks for our retails stores, we found that you either buy packages from companies like IBM or HP which are very expensive or there are people that custom make them. As I remember, the ones at Target would run you a lot of money especially since you are only going to need one and not 1000s. For our stores, I actually developed the app in VB using the Internet Explorer control which accessed our website. I programmed in all of the security and timeouts in conjunction with the functionality of the website. I would guess, you'll either spend a couple thousand at least buying a prebuilt product if not more.
