I'm not sure what to do about the AACOMAS costs, but you might be able to sidestep secondary app fees by writing heartfelt letters to the deans of the other schools explaining your situation and why you want to go there. Before you scoff, I've heard of several students forging agreements with hospitals to pay for ALL of their medical school in exchange for working there as a doctor. So it seems that problems can be worked out on an individual basis and exceptions can be made. Hope it works out.
