Clone of a program; paypal automation ebooks

I am looking for a professional company to clone a software from [login to view URL] What the software does is when someone pays you through paypal; the software will reconize the name of the product and will automatically email the ebook to the customers. This product must be upload to their hosting of their choose. Key features on the software: -admin login page -page showing item that have been purchased and the status of the delivery -saves every email address -payment reconizes the name of product, and send that product with email -program will not work if illegally downloaded or copied. There are more features of the program I have purchased this program; and you can view the details of this program from my hosting. I would like this to program to be created by only the best.
