Software Copy for Re Brand

I have some example Salon Software that I would like to be copied and then rebranded with my own logo and information. When installing the software there would be need for my own added security and product registration key. This software is going to be distributed in due course. The software will be able to be edited and updated by myslef when needed, but any major upgrades or changes I will come back to the project winner/completer. The view is to have the software versions upgraded every year to include any relevent changes and trends. This software will also have an email function for notifying clients of appointments. This feature is already present in my example software. I would like the software to have a fresh look and to make you want to use and own a copy. Software files will be available on FTP server for Project winner.
