Fair amount of Helo jobs available. The gotcha is that they all require ( or most any way, 1000-1500 helo PIC hours. There just are not many ways to build time in helo's except the military and as a helo instructor. I'd get my RW ratings right away if they didnt require those hours.... ( note here that I have in excess of 3300 hours already FW ).... Other than how to get the hours to get a RW job... your plan has some merit... although I am sure there are some here who will bash your ERAU choice.
