Diablo II - Lod : Item duplicate expliot / program

We are en global shop wich sells Diablo II items. We are looking for a program/expliot wich can dupelicate ingame items online (for making items for our shop ofc) We would prefer if the bidders know about Diablo II - LOD. The expliot/program must be able to do the following: The mothod must work on a max 2 ips (wich allow's to fill a game with 8 players) Work on the closed battle net (online server) And have a high % of working. The metod needs to be proved to work before any payment!, we have had many who said "We can do this" and we waited and waited and nothing happend (we made milestone payment, and lost the money). Note: In this case money is no problem
