Buy private miners. Expensive. Developers welcome.

[ivant]

Hi,
 Now I have 200 GPU farm (mainly r9 280x, and some r9 380x, gtx 970, gtx 980ti) and am going
to complete this year 180 GPU farm (rx 480).  I'm looking for opportunity to buy private miner
for AMD and Nvidia. I'm ready to pay 3-10 btc one time and your % dev-fee up to 20%.
I'd be glad long-term cooperation. I obligate keep in secret all information about your miners
and their characteristics (speed etc.). Of course, I obligate not to publish your miners.
 Write PM. Thnx.

PS: To convert deal I'm ready to use escrow of tried forum's members. I'm looking for real developer. Scammers, do not disturb.
