I am looking for a White Label software app that you have already created.

Hi there, I am looking to buy the resell rights to a software app for pc that you have already created.I want to market and resell a quality software application, this is not for the development of something new, but rather something that you have already created. The only thing I want to change is the name of the application (white label) the software. I do not care what the software does, as long as it works fine and is good quality. Could you also let me know how many copies of the software exists (how many people own a version of the app) I am willing to pay for work that you have already done (No new development work from your side.) Thanks.
