GI Bill

I currently have a PPL and am a check ride away from instrument. I am running low on cash and can't afford to go to school full time even with BAH and still pay my bills.

I would like to use my GI bill but am having trouble finding a school in the Dallas area that I can use it to complete my commercial cfi and cfii.

My goal is eventually the airlines but can't afford to support my family and train at the same time I need to be able to keep my job while I'm flying is my hurdle. Any advice?
