Hi, I've written a stock analysis software and instead of selling individual copies outright (as most people do), I would like to have it 'pay-per-use' over a website. It's a Windows program written in Delphi, that basically runs one big 'batch job' on the data of 3500 stocks and spits out recommendations. Ideally I'd like to have my software sitting on a server somewhere, the customer comes to my website, makes a small payment of a few dollars to Paypal (or some other payment processor), then gets access to my program over the web so he can run his one-time batch job analysis. Then when he's done, he logs out (or his allotted time expires and he gets logged out). And that's it.
So basically my first hurdle is - how can I run my Delphi program through a website? Maybe it's not even possible? Then once I can solve that, would look for a way to handle the "pay-per-use" side of it.
