I'd note that applying near the end of summer already puts you at a slight disadvantage as all the applications that flood in at the beginning of summer will be looked at before yours. While most schools won't start reviewing the applications until near the end of summer, they'll usually still go chronologically unless you did something to impress the admissions board enough that they specifically look for your name and pull you out of the pile.
I agree with above, call and try to set up a meeting with an admissions dean, but honestly, you'll be hard pressed to get that interview. They just graduated their class and right now, they are probably going on vacation, and when they get back, they'll be busy with greeting and hosting the incoming freshman, and when that's over, they'll have to start the admissions review process and this will keep them all very busy with full schedules for a while.
As for me, I'm a non-traditional too. I spent 3 years as a high school English Teacher, then 2 years as a working ceramic artist before deciding to go back to school. I got to know the associate dean at my two top picks about a year before I went on my interviews. At the interview I was lucky enough to get a faculty member who just wanted to talk about music the whole time.
Oh, I also got arrested 3 times...which came up in the interview...but I don't suggest you do that in the next two months.
