Diablo II closed realm dupe program

Hi, I need a dupe program for the game Diablo II LoD that works on closed battle.net. I can provide the game and as much cdkeys as needed (I have a couple hundreds in stock). I dont really care how good the program works what I need is more the how-to I can then make a program for myself. I have duping experience but the methods I know have been patched. I am only interested if it is possible to desynch a game without a max of 15-30 minutes or if you have a different method that use something else than games desynch. I will not resell the program to anyone. I can help developing a bot to automate the task since I am myself a programmer. Please post what you have to offer, requirements are pretty large, as long as you have something interesting to offer I will be interested. (I dont need any user-friendly crap) 100-300$ is my budget range, and I might consider a bonus depending how well this turns out. please estimate a deadline inyour bid.
