I cannot guarantee that I will be able to find a way to duplicate this items endlessly. Nobody truly can promise to find an exploit for sure.
However, I am a top security expert, and if there's a flaw to be found, I can find it. I will use proxies, VMs and many simulations to check how the game operates within the network to see if a flaw can be found.
If you'd like me to give more details, feel free to contact me. Further, I'd be happy to explain in greater detail how an exploit of this kind would work in case others bidding on the project make promises they cannot keep.
