that's what i am interested in ...
do you guys have any ideas on how to contact miners from china ?
Go to the Mining board on this Forum. Make your request to meet with a China miner. You may have to divulge your intent to get real interest. There are a few threads that share tours of mining operations, specifically from China. I'd start there. People on this forum are very helpful, you just need to find the expertise base you're looking for. Starting in the mining board will get you closer to that base of expertise (you won't find much of it "Beginners & Help".
And it sounds like you don't want to set up the operation on your own...if that's a correct assumption, why not? Operating these things are easy. Buy or lease a warehouse, buy a ton of mining machines, then pay someone to help you get the technical configuration correct (which probably isn't that hard). This way you take on all the risk but you also get all the reward and protect your investment from careless decision making by someone else.
Good luck to you!
