I'm interested but would you be willing to escrow or receive payment after set up and testing that everything works?
No! I don't trust escrows for some reasons and i will not set up for you and waste my time, i will do it only for some extra money
Edit: Now also included very easy manual how to set up on linux vps server
Price is still 50 USD Good luck then. It's a lot less reasonable for you to expect others here to trust going first to you than to trust an escrow here just because you think they would run away with what you're selling.
How much extra are you charging for setup? These scripts are notoriously known for having nearly zero documentation since they weren't initially created for commercial use. If I were to buy it, and I am interested, I would need a proper set up service.
