As an Admin, you should be an example to others here. This is considered as real world trading, and it isn't if this is a contest which is related to this game, but that's not the case here. You're asking for a service in which you offered something in return to it which is equal to real world trading.
You won't deserve anything in which your sweat isn't in it. Most people tend to be like this. When I was a teen, I have made a few profits easily in Wall Street without any effort but that was with some risk. Like anything worth anything, investing takes hard work and effort. That's a different story. But here, in a stingy manner; you're cheaply trying to rip-off people.
In the end, you will get what you deserve.
