Find the time, seriously you're after a multi-million dollar career. Do you want to half a$$ it? Look up Aerocrew solutions too, if you can't make an ECI session then maybe ACS has something closer.

That said, the online course will still help but you get a lot more out of it in person. When Aaron runs you through the mock interview with 10-15 other candidates there, you sweat. It sucks. Aaron gives you a full debrief of your performance. You can't get that over the internet. Plus if you're smart and do it plenty in advance of an interview you can mull over your notes, rethink things, and do another online course later to brush up or just do a quick phone rehack with Aaron and his crew.
