MOSFET circuit

Dear all,

I am wondering if there are any ways to change this circuit (Please see the attached file) to be one output, but I still can get 24V amplitude???
 

You need 4 Mosfets in an h-bridge.
Now, the Mosfets strongly pull down but the 4.7k resistors weakly pull up. So if you connect the load between them the load gets a weak current.

With an h-bridge the current is high in both directions.
 

If I use H-bridge, I will still have two outputs. One is '+' and the other one is '-'. However, I would like my circuit just has one signal output. So I can connect my system to the signal output and GND, but that output I would like to have 2 times of supply voltage; I don't really need very high current.
