I guess you give out some few copies for free with water mark at the footer leading people to where you're selling the script, seens it's new and you need sales you have to have few faucets running it that can help others know more about it and become interested. It's not easy to sell scripts without having a running and active faucet on it.
at first thanks for your comment and i'm glad you liked it
and i agree with you that is hard to sell new script
but i made ref commission for sharing it is 10% and i think it can help you can check this here:
