You should also think about raising salaries for the affiliate program. Some cloud minig services pay up to 10%.
I take a look on their tariffs from your link and I understand why there are 9%
Nobody will buy cloud mining with such prices And if nobody buys, you get nothing instead of 10% ))My post was more about that now entered to the market many cloud mining services and all of them fights for clients. Payments for signature campaigns and affiliate programs that's only tools but very important tools..
Just saying.. 
In my sig is just one link. Nice overview of signature campaigns (not only cloud minings services) you can find here:
