No offense, but at your prices you either haven't checked the profitability statistics in about 2 years or your trying to scam people who don't know any better.
You have a 10,000 KHS 24-hour contract for $113. However, checking the latest 24-hour coin profitability statistics, the best you can hope to make with such a contract is between $30-$40. Not exactly what one could consider a smart investment. In comparison, Scyptery has a similar 10,000KHS contract for about $45. It's still not profitable based on the latest profitability statistics, but it's much closer to reality.
Your "empty queue" prices would be decent, but there doesn't appear to be any sort of guaranteed minimum hashrate. In other words, it seems like someone could pay you $16 for 48 hours but end up getting 0 KHS if the queues are no longer "empty". That seems like a bit of a crapshoot there.
I also think similar like you so to test it I ordered the smallest package $1.99. I will post the result.
