hello im new to mine and i want to start mining.im ready to mine BTC XMR DASH ZEC ETH and some good stuff like these.
so what im proposing here is that : if anyone can help me for my ROI to make it under 7-8 Months i will give him 200 $ for his reward of doing that. i can spend up to 5K $ for the mining rig(GPU mining only), so anyone here can help me for that?

notice: " i will give rewar after i got my ROI
donot ever worry about reward.i would sign a contract for that if u want.

just answer me if u are sure about what u wanna do. only pros answer me. i wouldnt look at some newbs trying to do.

i donot want to try to make it under 7-8 months. answer me only when u are so sure that u can help me ROI under 5-6 Months.

Edit i can give up to 250 USD if anyone wanna help me out here
