It sounds to me like you are looking for a licensing mechanism.
There are a number of approaches to this, and one common way is to tie each license to a physical machine. When the customer decides to buy your software, they contact you with and send some data that your software gathers about their machine (such as NIC card id and hard drive id, and so on). You generate a license key based on their machine info hashed with a key that you provide.
Anyway - if you search google or msn for ".NET Licensing Schemes" you'll find enough reading to put you to sleep.

This is a big topic - but you can get a lot of very good information via the web doing a google search as I stated in my earlier post. That search is where you start. Once you have a basic understanding of what is typically done, if you have specific questions then I would be happy to try to answer. There will be many others here who will be able to also help.
