With a sizable amount of money that you want to get as quickly as possible, you also have to prepare big funds for initial capital too, but unfortunately in cloud mining you will only end up losing because all cloud mining is a scam, they don't run mining companies, they just run ponzi schemes like HYIPs, new members who register and deposit money will use the money to pay old members and so on and when no one is making deposits they will come out as a scam.
Don't waste your money, if you have capital it would be better to make your own mining setup if it doesn't go according to the target the equipment can be sold and you only experience a small loss.
