Get/Make a power board and control board.
You are going to need a control board and etched power board. The power board needs to be at least 3 ounce copper. Ebay is a good place to look for heavy cheap copper clad PCB. You could print this picture and press it onto a piece of heavy blank PCB, and etch it with a dremel if you have a very steady hand:

Picture 2 and 3 below is an example of an early power board I made with a Dremel.
You can get a control board from me or you can make the control board in your favorite PCB layout software using the schematic here:
