My suggestion is about the score killing.
We earn score by killing player's and some times we should earn a bit more. so why not add a score system (only the owner can set it)
So for example a player kills a enemy with a M4 and he only get's 1 point and 3000 cash. Why not add a double score booster. This can be only done when the owner dices to put it on.
The sever name will change saying "[DS] Desert Storm Army VS Terrorists[Double score time]" or something like that.
Just a easy way to earn more score/money
