GPU Rental (instead of hashrate)

@briceb8e Buying hashing power on NiceHash (for the purpose of mining Zcash/Equihash) could be a good option for you (as others already mentioned). You can read more about it here.

You basically buy hashing power for the price you set, NiceHash provides the miners and you decide on which pool they will mine for you. Mining usually lasts few hours or days (max. is 2 weeks).
