Um, I think that that's a bit ambitious. Your post is like speaking to a builder and saying:

Please tell me how to build a house. In fact, build a house for me.

There is lots of information out there about about designing and building n-tier apps in .NET so I suggest that you get out there and read some of it. Once you have enough information, try to design and build something. When you have a specific question to ask, e.g. "what does this mean" or "I tried X and Y happened instead of Z" then by all means post back and we can help you. We're not here to think for you though, or to write your code for you. My suggestion would be to write a simple app in one tier first and then try to modify it by extracting out first the data access logic and then the business logic.
