CONVERT A DESKTOP APPLICATION TO A WEB BASED APPLICATION

I have a software that was developed for me some years ago as a desktop application. I want to convert it into a web based application that people can simply access online and use it in such a way that it shows the same features and functionality on the web as it does when used offline. It basically does calculations and produces some reports already built into the software. If you can do this, I'd like you to bid, if and only if you have done a similar project to this before. The proof I need to know that you have done something similar is the sample of what you have done. SHOW ME AN EXAMPLE OF SOMETHING SIMILAR THAT YOU HAVE DONE. If you have not done something similar, you'd have to give me a convincing reason for me to believe that you can do something similar. I look forward to reading from you.
