Some questions that I'd love to get answered:

1. Is this web-script completely written by you/your developers and not currently in use by any other masternode hosting platform?
2. Does this script include any administrator-friendly/back-end interface or is it only about the front-end GUI?
3. Can't you temporarily make the platform online till you find a buyer? That'll help in understanding the stuff further.
4. It'll be great if you can include a rough estimate/worth that you believe you should get for the platform.
